A student working in the physics laboratory connects a parallel-plate capacitor to a battery, so that the potential difference between the plates is 230 V. Assume a plate separation of d = 1.51 cm and a plate area of A = 25.0 cm2. When the battery is removed, the capacitor is plunged into a container of distilled water. Assume distilled water is an insulator with a dielectric constant of 80.0. (a) Calculate the charge on the plates (in pC) before and after the capacitor is submerged. (Enter the magnitudes.) before Qi = pC after Qf = pC (b) Determine the capacitance (in F) and potential difference (in V ) after immersion. Cf = F ΔVf = V (c) Determine the change in energy (in nJ ) of the capacitor. ΔU = nJ (d) What If? Repeat parts (a) through (c) of the problem in the case that the capacitor is immersed in distilled water while still connected to the 230 V potential difference. Calculate the charge on the plates (in pC) before and after the capacitor is submerged.

A parallel-plate capacitor has charge of magnitude 8.40 μC on each plate and capacitance 2.40 μF when there is air between the plates. The plates are separated by 2.10 mm. With the charge on the plates kept constant, a dielectric with κ = 6 is inserted between the plates, completely filling the volume between the plates. (Enter the magnitudes.) (a) What is the potential difference between the plates of the capacitor (in V) before and after the dielectric has been inserted? before V after V (b) What is the electrical field at the point midway between the plates (in V/m) before and after the dielectric is inserted? before V/m after V/m
