When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Have you ever wondered about the electricity that courses through your car? Do you suspect that there's a captive bolt of lightning held in a magic jar? Of course you don't. You're not a Neanderthal.

AC and DC Current: AC (Alternating Current) and DC (Direct Current) are the two fundamental forms of electrical current, differing in how electricity flows through a circuit. Understanding this ...

Used to deliver power to your home, office, and any other building you can think of, alternating current (AC) voltage is relied on to provide power flawlessly on a daily basis. But why isn’t direct ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...
