Electrical Potential Energy and Electric Potential ** The gure below shows two point charges (11 = 3.50 X 103 C and (12 = 7.00 X 108 C. 10.0 20.0 Find the potential at A. Find the potential at B. Find the potential difference VA - VB. 3 \f*** Capacitance Three identical isolated capacitors, each with capacitance C, are connected in parallel, with a 12.0 V potential di'erence across their plates. Each capacitor carries a charge of 6.50 ,uC. Find C. Find the equivalent capacitance. Suppose that one of the capacitors is rst disconnected and. then reconnected with its terminals reversed. Find the nal voltage drop across the capacitors
