What happens to the charge on each plate if the capacitor remains connected to a battery while a dielectric is inserted? Because the charge is stranded in the capacitor plates, the charge cannot change. Adding the dielectric increases the capacitance by a factor of κ. Increasing C while keeping the charge the same means that […]
