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

For simple circuits, this can work, but for something complex (no pun intended), it gets hairy fast. By the way, this example showed to elements in series.

Circuit breakers are a safety feature that automatically interrupts the flow of electricity in the face of a system fault or ...

Sizing the circuit conductor. To correctly determine the minimum conductor size for a given ampacity, you first must determine the voltage drop for that circuit. You can do this by one of several ...

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 ...

Alternating current circuits improve the versatility and usefulness of electric power systems. In the late 1800s, Nikola Tesla demonstrated phenomena with alternating current (AC) electricity that ...

In a DC circuit, electrons move in one direction and keep rotating in the circuit. In an AC circuit, electrons don’t circulate and only move back and forth.

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

For the purely resistive circuit – for example, an incandescent light bulb – the power factor is 1 because the reactive power equals zero. Power factor can be an important aspect to consider in an AC ...
