The capacitance of a capacitor is 10 μF. The distance between the plates is made half and area is doubled. The capacitance of the capacitor will now be:

i think its 20 im not sure tho

  • physics -

    No. Capacitance is proportional to A/d.
    A doubles and d is reduced by half.
    Both changes have the effect of doubling the capacitance.

    Try again.

    What happens when you double something twice?

  • physics -

    so its 40?
