Physics

An uncharged capacitor is connected to the terminals of a 3.0 V battery, and 9.0 uC flows to the positive plate. The 3.0 V battery is then disconnected and replaced with a 8.0 V battery, with the positive and negative terminals connected in the same manner as before.

How much additional charge flows to the positive plate?

  1. Stored charge is proportional to voltage. It increases by a factor 8/3, becoming 9.0*(8/3) = 24 uC

    24 - 9 = ___ uC
