In this week’s Gizmodo University: Discover Electronics, we’re diving headfirst into the principle theories of electronics. The second of four classes in this series, “Volts, Amps, and Ohms” is ...

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: volts, ohms, and amps. Each describes a different piece of how electricity ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

Every student in physics and electronic engineering learns Ohm’s law, E = I x R, or voltage equals current times resistance. You learn that E is electromotive force, a long term for voltage. R is ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Electrical current is electrical charge transferred in a particular time. These three properties can be calculated using the equation Q=It. Current can be a.c. or d.c. Revise: Potential differences ...
