Ohm's law holds true for AC circuits, but voltage and current both increase and decrease together in a cycle while impedance remains constant. Anyone working within electrical systems must understand ...

In order to make sense of the Code, you must first understand basic electrical concepts such as voltage, amperage, resistance, Ohm's law, wattage, circuit theory and others.

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

June 30, 2014. Agilent Technologies Inc. has introduced a family of basic AC power sources that deliver stable, reliable power for testing electronic devices during design and manufacturing. The ...

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!

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

Conclusion It is essential to know the significant difference between an AC and DC isolator switch. Is a DC or AC circuit being created? Is an inductive or resistive switch to be used?
