1. What is the relationship between the electric field E and the electric potential V between the plates of the capacitor? Explain.

2. Where is the energy stored in a parallel-plate capacitor? Explain.

3. Let the energy stored "in the capacitor" be U. Show that U is given by the expression U = 1/2 Q2/C

[Hint: the power P in the capacitor is given by P = dU/dt = IV where I=dQ/dt. This is a simple exercise on integration.]

4. Calculate the energy stored in the capacitor network in the figure below when the capacitors are fully charged and when the capacitances are (in the photo below)
