Get started for freeWhat value resistor will discharge a capacitor to of its initial charge in ?
he switch in a closes at and, after a very long time, the capacitor is fully charged. Find expressions for
(a) the total energy supplied by the battery as the capacitor is being charged,
(b) total energy dissipated by the resistor as the capacitor is being charged, and
(c) the energy stored in the capacitor when it is fully charged. Your expressions will be in terms of E, R, and C.
(d) Do your results for parts a to c show that energy is conserved? Explain.
For what emf does the resistor in dissipate no power? Should the emf be oriented with its positive terminal at the top or at the bottom?
