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