Question

By taking the inverse transform of the current (V/R)/(s+1/RCe), the value of the current is?

(a) V/R e^t/Ce

(b) V/R e^t/RCe

(c) V/R e^-t/RCe

(d) V/R e^-t/Ce

Answer 1

The correct option is (c) V/R e^-t/RCe

Best explanation: By taking the inverse transform of the current, we obtain i = V/R e^-t/RCe which indicates that as R decreases, the initial current increases and the time constant decreases.
