Assume a device is designed to obtain a large potential difference by first charging a bank of capacitors connected in parallel and then activating a switch arrangement that in effect disconnects the capacitors from the charging source and from each other and reconnects them all in a series arrangement. The group of charged capacitors is then discharged in series. What is the maximum potential

difference that can be obtained in this manner by using ten 500-µF capacitors and an 800-V charging source? 1.500 V 2.8.00 kV 3.400 kV 4.800 V 5.0
