Question:

To repair a power supply for a stereo amplifier, an electronics technician needs a 100-µF capacitor capable of withstanding a potential difference of 90 V between its plates. The only available supply is a box of five 100-µF capacitors, each having a maximum voltage capability of 50 V. Can the technician substitute a combination of these capacitors that has the proper electrical characteristics, and if so, what will be the maximum voltage across any of the capacitors used?
