One ampere is the amount of current through a one-ohm resistance that has one volt of potential difference applied across it.

Question

Quizplus · Accepted Answer

According to Ohm's law, current (I) is equal to the voltage (V) divided by the resistance (R), so if there is a potential difference of one volt across a one-ohm resistor, the current flowing through it would indeed be one ampere (I = V/R = 1V/1Ω = 1A).
