D) the total energy of the charges in the circuit element.

Question

Quizplus · Accepted Answer

Resistance is defined as the ratio of voltage to current (Ohm's Law). It is a measure of how difficult it is for current to flow through a circuit element, and is usually measured in units of ohms (Ω). The larger the resistance, the greater the voltage required to produce a given current, and vice versa. Resistance is not a measure of work, circuit size or the total energy of charges.
