Connecting Capacitors in Series and in Parallel
Dielectric Example 2 Example: You have a capacitor with capacitance C 0, charge it up via a battery so the charge is +/- Q 0, with ΔV 0 across the plates and E 0 inside. Initially U 0 = 1/2C 0(ΔV 0)2 = Q 0 2/2C 0.Then, while keeping the connection to the battery
