A parallel-plate capacitor in air has a plate separation of, Ask an Expert

Academics

A parallel-plate capacitor in air has a plate separation of 1.50 cmand a plate area of 25.0cm². The plates arecharged to a potential difference of 2.50x10² V anddisconnected from the source. The capacitor is then immersedin distilled water. Determine (a) the charge on the plates before and after immersion, (b) the capacitance and potential difference after immersion, and (c) the change in energy stored in the capacitor due to immersion. Assume the distilled water is an insulator.
