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

question 237

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 $L = 50 \mathrm { H }$ , a resistor $R = 11 \mathrm { ohm }$ resistor, and a switch $\mathrm { S }$ . 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 $4.09 \mathrm {~s}$ after closing the switch?

• A) \(2.7 \mathrm {~A}\)
• B) \(2.2 \mathrm {~A}\)
• C) \(4.3 \mathrm {~A}\)
• D) \(5.5 \mathrm {~A}\)
• E) \(3.2 \mathrm {~A}\)
