The unit that represents the amount of resistance required to allow one amp through when one volt is applied is called a(n) ?.

Resistance is defined as the ratio of voltage to current, R = V / I. The unit that describes this ratio is the ohm. An ohm is the amount of resistance that will allow one ampere of current to flow when one volt of potential difference is applied. In other words, R = 1 V / 1 A = 1 Ω. That’s why the correct term is the ohm. The amp is a unit of current, the volt is a unit of voltage, and the watt is a unit of power, so they don’t represent resistance. A 1-volt drop with 1 amp of current illustrates the definition of 1 ohm.
