An uncharged capacitor is connected to the terminals of a 2.0 V battery, and 12 ?C flows to the positive plate. The 2.0 V battery is then disconnected and replaced with a 6.0 V battery, with the positive and negative terminals connected in the same manner as before.How much additional charge flows to the positive plate?
