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

question 16

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