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

question 63

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
