Question 31

Which of the following descriptions correctly represents the behavior of the potential difference VCV_CVC​ across the supercapacitor and the magnitude of the current III in the circuit against time ttt as the supercapacitor charges?

A

Both VCV_CVC​ and III start at zero at t=0t = 0t=0 and increase exponentially towards constant maximum values.

B

VCV_CVC​ starts at zero and increases exponentially towards VsV_sVs​, while III starts at a maximum value VsR\frac{V_s}{R}RVs​​ and decreases exponentially to zero.

C

VCV_CVC​ starts at VsV_sVs​ and decreases exponentially to zero, while III starts at zero and increases exponentially to a maximum value VsR\frac{V_s}{R}RVs​​.

D

Both VCV_CVC​ and III start at maximum values at t=0t = 0t=0 and decrease exponentially to zero.
