Review

For the equivalent capacitor alone, of capacitance \(C_{\mathrm{equiv}}\), Equation 17-14 says that \(q=C_{\mathrm{equiv}}V\) or \(V = q/C_{\mathrm{equiv}}\). If we compare this to Equation 17-21, we see that

If there are more than three capacitors in series, the same rule given in Equation 17-22 applies.
