The circuit shows a capacitor, two ideal batteries, two resistors and a switch. Initially the switch has been open for a long time. If it is then closed for a long time, what is the change in the charge on the capacitor?
Assume that $R_1 = 620 \, \Omega$, $R_2 = 280 \, \Omega$, $C = 770 \, \mu F$, $V_1 = 6 \, V$ and $V_2 = 15 \, V$.
The change in the charge on the capacitor is equal to $\mu C$
