The amount of induced voltage in an inductor can be computed if the resistance of the wire in the coil and ____ are known.
A) the amount of circuit current
B) the length of the circuit
C) any alternating current sources
D) its capacitance

Question

Quizplus · Accepted Answer

The induced voltage in an inductor is directly proportional to the rate of change of current through the coil. This change in current is determined by the circuit current flowing through the inductor and the resistance of the wire in the coil. Therefore, if the resistance and circuit current are known, the induced voltage can be calculated using Faraday's law of electromagnetic induction. The other options, such as length of the circuit, any alternating current sources, and its capacitance do not directly affect the induced voltage in an inductor.
