A parallel-plate capacitor in air has a plate separation of 1.35 cm and a plate area of 35.0 cm2. The plates are charged to a potential difference of 150 V and disconnected from the source. The capacitor is then immersed in distilled water. Assume the liquid is an insulator. Determine: a. the charge on the plates before and after immersion b. the capacitance and potential difference after immersion c. the change in energy of the capacitor after immersion
