A 5.00 ptF parallel-plate capacitor is connected to a 12.0 V battery. After the capacitor is fully charged; the battery.r is disconnected without loss of any of the charge on the plates. Part A A voltmeter is connected across the two plates without discharging them. What does it read?Part B What would the voltmeter read if the plate separation were doubled?Part C What would the voltmeter read if the radius of each plate were doubled; but their separation was unchanged\
