Physics - Current Electricity Question with Solution | TestHub

A capacitor of capacitance$\mathrm{C}$is charged to a potential difference$\mathrm{V}$and then connected in series with an open key and a pure resistor$\mathrm{R}$. At time$\mathrm{t}=0$, the key is closed. If$\mathrm{I}$is current at time$\mathrm{t}=0$, a plot of$\log \mathrm{I}$against$\mathrm{t}$is shown in the graph$\left(2\right)$. Later one of the parameters, i.e.,$\mathrm{V}$,$\mathrm{R}$and$\mathrm{C}$is changed, keeping the other two constant and graph$\left(2\right)$is recorded. Then
