Question 52

Multiple Choice

An inductor with inductance L restistor with resistance R are wired in series to an ideal battery with emf ε\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, ε\varepsilon
B) are ε\varepsilon , 0
C) are ε\varepsilon /2, ε\varepsilon /2
D) (L/R) ε\varepsilon , (R/L) ε\varepsilon
E) unknown since the rate of change of the current is not given
