2 Basic ideas 12/14/2007 Electric current is when electrons start to flow around a circuit. We use an to measure it and it is measured in. Potential difference (also called ) is how big the push on the electrons is. We use a to measure it and it is measured in, a unit named after Volta. Resistance is anything that resists an electric current. It is measured in. WORDS: volts, amps, ohms, voltage, ammeter, voltmeter
