An Inductor with Inductance L Restistor with Resistance R Are $\varepsilon$

question 52

Multiple Choice

An inductor with inductance L restistor with resistance R are wired in series to an ideal battery with emf $\varepsilon$ . A switch in the circuit is closed at time 0, at which time the current is zero. A long time after the switch is thrown the potential differences across the inductor and resistor:

• A) are 0, \(\varepsilon\)
• B) are \(\varepsilon\), 0
• C) are \(\varepsilon\)/2, \(\varepsilon\)/2
• D) (L/R)\(\varepsilon\), (R/L)\(\varepsilon\)
• E) unknown since the rate of change of the current is not given
