Homework Help: Min voltage rating of capacitor

  1. May 7, 2006 #1
    i was solving a prob the foll prob on electrical resonance.

    a resistance is connected in series with an inductor which inturn is connected to 2 capacitors(capacitors are in parallel w.r.t each other, and one of them is trimming capacitor).the circuit is now connected to a relay whose inductance and resistance is given.
    v=10v
    resonant freq=1600 hz
    C=100nf
    L=90mH
    R=130ohms
    ...............
    i have found the value of the trimming capacitor Ct=9.9nF
    using F=1/2pi sqr rt of LC
    and then using ohms law i have found the max operating current of the relay.
    i am confused as to what is meant by min voltage rating of a capacitor(which i need to find)
