Effect of Dielectric Charging and Discharging of Capacitor
Capacitance

165959 A capacitor is discharged through a resistance in $R-C$ circuit. The variation of $\log _{e} i$ with time $t$ is shown by a dotted line in the figure, where $i$ is the discharging current. If the resistance in the circuit be doubled, the variation of $\log _{e} i$ with time $t$ would be best represented by the line
