As the resistance of an LR circuit is increased:
A) self-inductance is partially reduced
B) the circuit time constant is increased.
C) induced voltage is greatly increased
D) the circuit time constant is decreased.

Question

Quizplus · Accepted Answer

The time constant of an LR circuit is given by $\tau = \frac{L}{R}$, where $L$ is the inductance and $R$ is the resistance. Increasing the resistance $R$ decreases the time constant $\tau$, making the circuit respond faster to changes.
