Reference no: EM13560624

A 150 pF capacitor is charged to a potential difference of 64 V, and the charging battery is disconnected. The capacitor is then connected in parallel with a second (initially uncharged) capacitor. If the measured potential difference across the first capacitor drops to 30 V, what is the capacitance of this second capacitor?
