A physicist connects a 3.50 V battery to the plates of a capacitor. After waiting a while, the capacitor reaches a maximum amount of 25.0 µC of stored charge. What is the value of the capacitance (in µF)?
The capacitor is disconnected from the battery, discharged, and then connected to a 20.0 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 capacitor
