Voltage explained. What is voltage and what does it do? In this video we discuss how it work and its purpose to understand how electricity works. We'll look at voltage for both alternating current and direct current starting off very simply and slowing building up as we go along to build your base knowledge including how to measure voltage with a multimeter.
Volts, Voltage, Current, Amps, Ampere, Circuits, Electronics, potential difference joule 220v
