In the following circuit, the switch S is closed at t = 0. The charge on the capacitor C1 as a function of time will be given by $\left( {{C_{eq}} = {{{C_1}{C_2}} \over {{C_1} + {C_2}}}} \right)$

Question

In the following circuit, the switch S is closed at t = 0. The charge on the capacitor C₁ as a function of time will be given by $\left( {{C_{eq}} = {{{C_1}{C_2}} \over {{C_1} + {C_2}}}} \right)$

${C_1}E\left[ {1 - \exp \left( { - tR/{C_1}} \right)} \right]$

${C_2}E\left[ {1 - \exp \left( { - t/R{C_2}} \right)} \right]$

${C_{eq}}E\left[ {1 - \exp \left( { - t/R{C_{eq}}} \right)} \right]$

${C_{eq}}E\,\,\exp \left( { - t/R{C_{eq}}} \right)$
