The capacitor is connected to a battery with emf = 8.0 V and after equilibrium is reached, the capacitor is disconnected from the battery. Then the plastic is removed. How
much charge is now on the plates?
Homework Answers
Since the charge is always conserved, the charge on the capacitor would be the same as it was initially.

a.) A lab technician connects a 4.50 V battery to the plates of a capacitor. After waiting a while, the capacitor reaches a maximum amount of 21.0 µC of stored charge. What is the value of the capacitance (in µF)? b.) The capacitor is disconnected from the battery, discharged, and then connected to a 15.0 V battery. Again, a long enough time is waited for the capacitor to fully charge. How much charge (in µC) is stored now? (Assume the...
