Question

While discharging, what happens to the current in the capacitive circuit?

(a) Decreases linearly

(b) Increases linearly

(c) Decreases exponentially

(d) Increases exponentially

Answer 1

The correct answer is (d) Increases exponentially

Best explanation: The equation for the value of current in a discharging capacitive circuit is:

I=I0(1-e^-t/RC). From this equation, we can see that the current is exponentially increasing.
