The Series Circuit Shown in the Figure Contains an Ideal $V _ { \mathrm { B } } = 60 \mathrm {~V}$

Multiple Choice

The series circuit shown in the figure contains an ideal battery with a constant terminal voltage $V _ { \mathrm { B } } = 60 \mathrm {~V}$ , an ideal inductor $L = 42 \mathrm { H }$ , a resistor $R = 24$ ohm resistor, and a switch S.Initially, the switch is open, and there is no current in the inductor. At time $t = 0 \mathrm {~s}$ , the switch is suddenly closed. What is the current in the circuit when the voltage across the resistor is equal to the voltage across the inductor?

A) $0.75 \mathrm {~A}$
B) $1.0 \mathrm {~A}$
C) $0.50 \mathrm {~A}$
D) $1.3 \mathrm {~A}$
E) $1.5 \mathrm {~A}$
