A circuit consists of a battery of emf $V$, a resistor of resis\tance $R$, and an inductor of induc\tance $L$. If the circuit is connected to a switch, calculate the current in the circuit at time $t$.

Answer Options

Correct Answer A. ( i(t) = \frac{V}{R} \( 1 - e^{-\frac{Rt}{L}} \) )
B. ( i(t) = \frac{V}{R} \( 1 + e^{-\frac{Rt}{L}} \) )
C. ( i(t) = \frac{V}{R} \( e^{-\frac{Rt}{L}} \) )
D. ( i(t) = \frac{V}{R} \( e^{\frac{Rt}{L}} \) )
Correct Answer
A
Correct Option:
( i(t) = \frac{V}{R} \( 1 - e^{-\frac{Rt}{L}} \) )
