An 80-MH Inductor and a 2 $\Omega$ Resistor Are Wired in Series to a 20-V Ideal Battery

Multiple Choice

An 8.0-mH inductor and a 2.0- $\Omega$ resistor are wired in series to a 20-V ideal battery.A switch in the circuit is closed at time t = 0, at which time the current is zero.Immediately after the switch is thrown the potential differences across the inductor and resistor are:

A) 0 V, 20 V
B) 20 V, 0 V
C) 10 V, 10 V
D) 16 V, 4 V
E) unknown since the rate of change of the current is not given
