Find the inductor current after the switch closes in the circuit.

A. \(i\left( t \right) = 4\;\left( {1 + {e^{ - \frac{t}{5}}}} \right)\) mA, and t is in μs
B. \(i\left( t \right) = 4\;\left( {1 + {e^{ \frac{t}{5}}}} \right)\)mA, and t is in μs
C. \(i\left( t \right) = 4\;\left( {1 - {e^{ - \frac{t}{5}}}} \right)\) mA, and t is in μs
D. \(i\left( t \right) = 4\;\left( {1 - {e^{ \frac{t}{5}}}} \right)\) mA, and t is in μs
Answer» D. \(i\left( t \right) = 4\;\left( {1 - {e^{ \frac{t}{5}}}} \right)\) mA, and t is in μs
