Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.
AC is the form in which electric power is delivered to businesses and residences. The usual waveform of alternating current in most electric power circuits is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves.
Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video). These currents typically alternate at higher frequencies than those used in power transmission.
Transmission, distribution, and domestic power supply
Electric power is distributed as alternating current because AC voltage may be increased or decreased with a transformer. This allows the power to be transmitted through power lines efficiently at high voltage, which reduces the power lost as heat due to resistance of the wire, and transformed to a lower, safer, voltage for use. Use of a higher voltage leads to significantly more efficient transmission of power. The power losses () in a conductor are a product of the square of the current (I) and the resistance (R) of the conductor, described by the formula
In this video, we'll teach you about Alternating Current (AC), and how it works. We'll discuss the types of AC, and how they're used in everyday life.

AC Circuits: Crash Course Physics #36
We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or alternating currents). We’ve talked about how they change voltage, which helps transmit electricity over long distances, but there’s so much more to the physics of AC circuitry.

Why Use AC Instead of DC at Home??
Isn’t AC more dangerous than DC?? So why do we use AC instead of DC to power our homes? Did we go wrong somewhere?

In this video, we look at direct current (DC) and alternating current (AC). First we explore what is meant by these two types of current and then we look at how to use an oscilloscope trace to determine the features of an AC supply.
This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.

We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or alternating currents). We’ve talked about how they change voltage, which helps transmit electricity over long distances, but there’s so much more to the physics of AC circuitry.

This video demonstrates alternating current with one-phase power in detail, providing specific examples. Alternating current is electric current that reverses its direction many times a second at regular intervals.
To learn more visit: http://www.raritan.com/
Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.
AC is the form in which electric power is delivered to businesses and residences. The usual waveform of alternating current in most electric power circuits is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves.
Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video). These currents typically alternate at higher frequencies than those used in power transmission.
Transmission, distribution, and domestic power supply
Electric power is distributed as alternating current because AC voltage may be increased or decreased with a transformer. This allows the power to be transmitted through power lines efficiently at high voltage, which reduces the power lost as heat due to resistance of the wire, and transformed to a lower, safer, voltage for use. Use of a higher voltage leads to significantly more efficient transmission of power. The power losses () in a conductor are a product of the square of the current (I) and the resistance (R) of the conductor, described by the formula
