As Shown in the Figure, a Circuit Consists of a Resistor

question 187

Multiple Choice

As shown in the figure, a circuit consists of a resistor $R = 18 \Omega$ in series with an ideal inductor $L = 33 \mathrm { H }$ having no resistance. At time $t = 0 \mathrm {~s}$ , there is a 12-A current in the circuit. When the magnetic energy of the inductor is $1600 \mathrm {~J}$ , what is the rate of dissipation of energy in the resistor?

• A) \(1700 \mathrm {~W}\)
• B) \(2200 \mathrm {~W}\)
• C) \(870 \mathrm {~W}\)
• D) \(1300 \mathrm {~W}\)
• E) \(440 \mathrm {~W}\)
