The time constant of an inductor is:
A)inversely proportional to the resistance in the circuit.
B)the time required forVoltage or current to increase to 63% or to decrease to 37%.
C)directly proportional to the inductance in the circuit.
D)all of these.

Question

Quizplus · Accepted Answer

The time constant of an inductor is indeed inversely proportional to the resistance in the circuit, directly proportional to the inductance in the circuit, and defined as the time required for the current or voltage to increase to 63% of its maximum value or decrease to 37% of its maximum value in response to a step change. Therefore, all of these statements are correct descriptions of the inductor's time constant.
