Q. In $L$-$R$ circuit, for the case of increasing current, the magnitude of current can be calculated by using the formula
A) $I = I_{0}e^{- Rt/L}$
B) $I = I_{0}(1 - e^{- Rt/L})$
C) $I = I_{0}(1 - e^{Rt/L})$
D) $I = I_{0}e^{Rt/L}$
Explanation
The correct answer is Option B: $I = I_{0}(1 - e^{- Rt/L})$.
