A varying voltage is applied to the clamps AB as shown in fig. such that the voltage across the capacitor plates varies as shown in the figure. Plot the time depending on voltage across the clapes CD.

Explanation

For `t =t_(0) = 2t_(0), V =at + b`
Charge on capacitor `q= CV =C[at+ b]`
Current `I = (dq)/(dt) Ca rarr constant`

Potential across `CD = IR = CaR rarr constant`
