Homework Help: Combination of capacitors

  1. Feb 7, 2004 #1
    to repair a power supply for a stereo amplifier, an electronics technician needs a 100-uF(microfarads) capacitor capable of withstanding a potential difference of 90V between the plates. the only available supply is a box of five 100-uF (microfarads) capacitors. each having a maximum voltage capability of 50V. Can the technician substitute a combination of these capacitors that has the proper electrical characteristics? if so, what will be the maximum voltage across any of the capacitors used? (suggestion: the technician may not have to use all the capacitors in the box)
    ---
    there are at lest 2 possbilities, and i know the maximum voltage is 45V.
