Circuits With Resistors And Inductors (lr Circuits) — Quiz
Test your understanding of circuits with resistors and inductors (lr circuits) with 5 practice questions.
Practice Questions
Question 1
In an $LR$ circuit, what does the inductor mainly do when the current first starts to increase after a battery is connected?
Question 2
What is the time constant of a series $LR$ circuit with resistance $R$ and inductance $L$?
Question 3
A steady current has been flowing in an $LR$ circuit for a long time. At that moment, how does the inductor behave?
Question 4
In a series $LR$ circuit connected to a battery, which statement best describes the current immediately after the switch is closed?
Question 5
Which expression gives the current growth in a series $LR$ circuit after a battery of emf $V$ is connected at $t=0$?
