A circuit consists of a battery of emf $\mathcal{E}$, a resistor of resis\tance $R$, and an inductor of induc\tance $L$. The circuit is connected to a switch that is closed at time $t=0$. What is the current in the circuit at time $t$?

Answer Options

Correct Answer A. \frac{\mathcal{E}}{R} \left\( 1 - e^{-\frac{R}{L} t} \right \)
B. \frac{\mathcal{E}}{R} \left\( 1 + e^{-\frac{R}{L} t} \right \)
C. \frac{\mathcal{E}}{R} \left\( 1 - e^{\frac{R}{L} t} \right \)
D. \frac{\mathcal{E}}{R} \left\( 1 + e^{\frac{R}{L} t} \right \)
Correct Answer
A
Correct Option:
\frac{\mathcal{E}}{R} \left\( 1 - e^{-\frac{R}{L} t} \right \)
