Power in an electric circuit is the rate of energy consumption or production as currents flow through various parts comprising the circuit. In alternating current circuits, immediate power transferred through any phase varies periodically. Energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. The portion of power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as active power (sometimes also called real power). The portion of power due to stored energy, which returns to the source in each cycle, is known as reactive power.
Active, reactive, and apparent power
In a simple alternating current (AC) circuit consisting of a source and a linear load, both the current and voltage are sinusoidal. If the load is purely resistive, the two quantities reverse their polarity at the same time. At every instant the product of voltage and current is positive or zero, with the result that the direction of energy flow does not reverse. In this case, only active power is transferred.

Power Factor - Basic Introduction - Reactive and Apparent Power.
This electronics video tutorial provides a basic introduction into power factor. The power factor is the ratio of the true power to the apparent power. It's also equal to the resistance divided by the impedance. The reactive power can be calculated using the power triangle and the pythagorean theorem or you can calculate it using the capacitive / inductive reactance and the rms current flowing in the circuit.

How Three Phase Electricity works - The basics explained
SEE NEW VIDEO HERE: https://youtu.be/c9gm_NL7KyE
In this video we learn how three phase electricity works from the basics. The basics of Three phase electricity explained. We start with a simple single phase AC generator and then add in a second and third phase to under stand its working principle. We also cover three phase power uses and distribution as well as why we don't use more phases.

This electronics video tutorial provides a basic introduction into power factor. The power factor is the ratio of the true power to the apparent power. It's also equal to the resistance divided by the impedance. The reactive power can be calculated using the power triangle and the pythagorean theorem or you can calculate it using the capacitive / inductive reactance and the rms current flowing in the circuit.

In this video we learn how three phase electricity works from the basics. The basics of Three phase electricity explained. We start with a simple single phase AC generator and then add in a second and third phase to under stand its working principle. We also cover three phase power uses and distribution as well as why we don't use more phases.

What is AC power? What is an alternating current? How is an alternating current generated? Alternating currents are exactly what they sound like. A flow of electrons that changes direction - an alternating current! This video explains how they are created, in a simplified manner.

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.

Power in an electric circuit is the rate of energy consumption or production as currents flow through various parts comprising the circuit. In alternating current circuits, immediate power transferred through any phase varies periodically. Energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. The portion of power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as active power (sometimes also called real power). The portion of power due to stored energy, which returns to the source in each cycle, is known as reactive power.
Active, reactive, and apparent power
In a simple alternating current (AC) circuit consisting of a source and a linear load, both the current and voltage are sinusoidal. If the load is purely resistive, the two quantities reverse their polarity at the same time. At every instant the product of voltage and current is positive or zero, with the result that the direction of energy flow does not reverse. In this case, only active power is transferred.
