A parallel-plate capacitor in air has a plate separation of 1.64cm and a plate area of 24.8cm2. The plates are charged to a potential difference of 260.V and disconnected from the source. The capacitor is then immersed in distilled water. Determine the charge on the plates before immersion. Neglect the conductance of the liquid. Determine the charge on the plates after immersion. Calculate the capacitance after immersion. Calculate the voltage after immersion. Calculate the change in energy of the capacitor.
