What is Capacitor - Types, Formula, Symbol, ‎How it Works, Unit

?20% Part (a) Express the capacitance C of a capacitor in terms of charge Q and voltage ?V on it.?20% Part (b) Apply the above formula to capacitor $C1$ to find an expression for the potential difference $?V{12}$ across it.?20% Part (c) Express the potential difference $?V{12}$ through potentials $V1$ and $V2$ where $V1$ and $V2$ are the potentials measured in the wires 1 and 2,respectively, relative to the negative side of the battery.?20% Part (d) Calculate $V2$ in V given $V1 = 9$ V.?20% Part
