Question 1 You build a parallel plate capacitor from two 5.80 cm diameter aluminum disks and 0.840 mm rubber spacers. You then connect your capacitor to a 64.0 V battery; after the capacitor is fully charged, how much charge is on the positive electrode? 1.78 nC 4.53 nC 2.20 nC 0.220 nC Question 2 You happen to have three capacitors with values of 11.0 uF, 25.0 uF, and 28.0 uF. If you connect them together in series, what is their equivalent capacitance? 0.0156 uF 0.167 uF 64.0 uF 6.00 uF Question 3 A debrillator is a device that sends an electric pulse to the heart to restore a normal heartbeat. It delivers the pulse using an internal capacitor that is charged by a battery. Suppose a certain debrillator has a capacitance of 71 .0 uF, and when used supplies an average of 8.95x103 W of power to the chest of the patient over a time lasting only 4.70 ms. To what voltage is the capacitor charged? 1 .82x103 V/m 1.09x103 V/m 553 V/m 2.67x103 V/m
