Mains electricity is the general-purpose alternating-current (AC) electric power supply. In the US, mains electric power is referred to by several names including household power, household electricity, house current, powerline, domestic power, wall power, line power, AC power, city power, street power, and grid power.
The two principal properties of the electric power supply, voltage and frequency, differ between regions. A voltage of (nominally) 230V and a frequency of 50Hz is used in Europe, most of Africa, most of Asia, most of South America and Australia. In North America, the most common combination is 120V and a frequency of 60Hz. Other voltages exist, and some countries may have, for example, 230V but 60Hz. This is a concern to travelers, since portable appliances designed for one voltage and frequency combination may not operate or may be destroyed by another.
The use of different plugs and sockets in different regions provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.

MAINS ELECTRICITY | Sources of mains electricity & Power transmission
An electrical grid is an interconnected network for delivering electricity from producers to consumers.
It consists of generating stations that produce electrical power, high voltage transmission lines that carry power from distant sources to consumers.
Power stations are located near a fuel source, e.g. a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas. The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network.
The bulk power transmission network will move the power over long distances until it reaches its consumers.
On arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution level voltage....

Wires | Electricity | Physics | FuseSchool
A broken wire means two things;
1. It won’t work properly anymore.
2. It’s dangerous and shouldn’t be used.
In this video we’re going to look at wires, the wiring of a plug and why insulation is important.
Wires inside walls carry electricity to electrical sockets and lights in a house.
Whenever you plug in an appliance, you’re connecting it to an electrical circuit.
A appliance is anything that transfers energy from one form to another.
Different countries have different plugs, for connecting devices to the mains.
Each of the pins in the plug is connected to a different type of wire. We’re going to look at a 3 pin plug with 3 wires, but 2 pins are pretty much the same.
If we look inside a plug we can see the different wires.
The brown live wire
The blue neutral
And the green and yellow earth.
The brown live wire and the blue neutral wire carry the current around the circuit.
The live wire is the route into the plug for the electric current. The current is alternating current, which travels back and forth approximately 50 times a second.
The neutral wire completes the circuit. It is the route the electric current takes when it exits an appliance. Neutral wires have a voltage close to zero.
The green and yellow earth wire is a safety wire. Many electrical appliances have metal casings.
If a loose wire touches the metal casing, anyone who touches the appliance would get an electrical shock. Which is where the earth wire comes in. The earth wire connects to the earth pin, which takes the current away from the appliance into the wiring of your house and down to the earth through the house’s earthing system. So the current runs through the earth wire, rather than running through you if you touch the appliance. Much safer!
The earth pin on a plug is longer than the live and neutral pins. Therefore whenever you plug in a plug, the earth pin always connects with the socket first. Providing you with that earthing safety.
The fuse is a very thin wire between the live terminal and the live pin. It has a very low melting point, so if a too large current flows through the fuse, then the wire heats up and melts. Thus breaking the circuit. Which is why you might hear the phrase “the fuse has blown”. If there is a gap in the circuit, electricity cannot flow and so the device will not work, but the user is safe.
The main role of a fuse is to prevent fires starting, due to too large currents.
Another safety feature is the outer insulation of wires attached to plugs.
Plastic is an electrical insulator meaning electricity cannot travel through it. If electrical wires are surrounded by a plastic casing, then they are safe to touch. If there is a break in the plastic or it is damaged, you could come into contact with the wire inside and have an electrical shock. So do yourself a favour, if your phone charger looks like this, get yourself a new one!
Different countries have slightly different colour combinations for these wires, but they’re pretty much the same.
There’s a really easy way to remember where each wire goes…
Take the 2nd letters of the colours
BLue L Left
BRown R Right
STriped T Top
So there we have our current carrying live and neutral wires, and our protective earth wire and fire stopping fuses.

An electrical grid is an interconnected network for delivering electricity from producers to consumers.
It consists of generating stations that produce electrical power, high voltage transmission lines that carry power from distant sources to consumers.
Power stations are located near a fuel source, e.g. a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas. The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network.
The bulk power transmission network will move the power over long distances until it reaches its consumers.
On arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution level voltage. As it exits the substation, it enters the distribution wiring. Finally, upon arrival at the service location, the power is stepped down again from the distribution voltage to the required service voltage(s).

Wires | Electricity | Physics | FuseSchool
A broken wire means two things;
1. It won’t work properly anymore.
2. It’s dangerous and shouldn’t be used.
In this video we’re going to look at wires, the wiring of a plug and why insulation is important.
Wires inside walls carry electricity to electrical sockets and lights in a house.
Whenever you plug in an appliance, you’re connecting it to an electrical circuit.
A appliance is anything that transfers energy from one form to another.
Different countries have different plugs, for connecting devices to the mains.
Each of the pins in the plug is connected to a different type of wire. We’re going to look at a 3 pin plug with 3 wires, but 2 pins are pretty much the same.
If we look inside a plug we can see the different wires.
The brown live wire
The blue neutral
And the green and yellow earth.
The brown live wire and the blue neutral wire carry the current around the circuit.
The live wire is the route into the plug for the electric current. The current is alternating current, which travels back and forth approximately 50 times a second.
The neutral wire completes the circuit. It is the route the electric current takes when it exits an appliance. Neutral wires have a voltage close to zero.
The green and yellow earth wire is a safety wire. Many electrical appliances have metal casings.
If a loose wire touches the metal casing, anyone who touches the appliance would get an electrical shock. Which is where the earth wire comes in. The earth wire connects to the earth pin, which takes the current away from the appliance into the wiring of your house and down to the earth through the house’s earthing system. So the current runs through the earth wire, rather than running through you if you touch the appliance. Much safer!
The earth pin on a plug is longer than the live and neutral pins. Therefore whenever you plug in a plug, the earth pin always connects with the socket first. Providing you with that earthing safety.
The fuse is a very thin wire between the live terminal and the live pin. It has a very low melting point, so if a too large current flows through the fuse, then the wire heats up and melts. Thus breaking the circuit. Which is why you might hear the phrase “the fuse has blown”. If there is a gap in the circuit, electricity cannot flow and so the device will not work, but the user is safe.
The main role of a fuse is to prevent fires starting, due to too large currents.
Another safety feature is the outer insulation of wires attached to plugs.
Plastic is an electrical insulator meaning electricity cannot travel through it. If electrical wires are surrounded by a plastic casing, then they are safe to touch. If there is a break in the plastic or it is damaged, you could come into contact with the wire inside and have an electrical shock. So do yourself a favour, if your phone charger looks like this, get yourself a new one!

An electrical grid is an interconnected network for delivering electricity from producers to consumers.
It consists of generating stations that produce electrical power, high voltage transmission lines that carry power from distant sources to consumers.
Power stations are located near a fuel source, e.g. a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas. The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network.
The bulk power transmission network will move the power over long distances until it reaches its consumers.
On arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution level voltage. As it exits the substation, it enters the distribution wiring. Finally, upon arrival at the service location, the power is stepped down again from the distribution voltage to the required service voltage(s).
The video explains the function of the feeder, distributor and service mains in electrical distribution system. Feeder, Distributor & Service Mains are very important and easy terms to understand. What is feeder in power system? This video explains these terms in a very easy way!

Mains electricity is the general-purpose alternating-current (AC) electric power supply. In the US, mains electric power is referred to by several names including household power, household electricity, house current, powerline, domestic power, wall power, line power, AC power, city power, street power, and grid power.
The two principal properties of the electric power supply, voltage and frequency, differ between regions. A voltage of (nominally) 230V and a frequency of 50Hz is used in Europe, most of Africa, most of Asia, most of South America and Australia. In North America, the most common combination is 120V and a frequency of 60Hz. Other voltages exist, and some countries may have, for example, 230V but 60Hz. This is a concern to travelers, since portable appliances designed for one voltage and frequency combination may not operate or may be destroyed by another.
The use of different plugs and sockets in different regions provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.
