We've talked about how AC circuits change voltage, but let's take a deeper look.

To show power relationships in ac circuits, it is often convenient to start with the well-known phasor diagram representation of an ac circuit: ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two ...

This circuit offers an alternative to a bulky, noisy, vibration/magnetic field/heat producing transformer. However, the advantage of the transformer is in the isolation it offers from live AC. The ...

However, this rarely happens and only in alternating current (AC) circuits containing pure resistances. Most AC circuits contain some type of inductance, in which case the current waveform lags the ...

Like most other simple circuits, this circuit also has a disadvantage: It is incompatible with some load-power and ac-mains-voltage values. When a fuse burns out, the load stays connected to the ac ...

Thomas Edison favored DC circuits, but Nikola Tesla thought AC circuits were the way to go. Clearly Tesla won that argument. Let’s see why!
