how many 0.25-pF capacitors must be connected in parallel in order to store 1.2uC of charge when connected to a battery providing a potential difference of 10v?

  1. Damon

    C = q/V
    q = C V
    so each stores 2.5 * 10^-12 C
    so we need 1.2*10^-6/2.5*10^-12 = .48*10^6

  2. Steve

    1.2x10^-6 / 0.25x10^-12 = 4.8x10^6

  3. Damon

    but C times ten volts = q per capacitor
