Trivia: What unit is used to measure electrical currents?
Ohm
Watt
Volt
Ampere
The correct answer is Ampere
So why is this answer correct? : Amperes, or amps, are used to measure electrical current. This unit basically counts how many electrons are flowing through an electrical circuit at any given time. Other measurements include volts (units that measure how big the force pushing the current is) and ohms (the measurement of resistance to electrical current).
