Part A When an air capacitor with a capacitance of 270 nF (1 nF = 10 F) is connected to a power supply, the energy stored in the capacitor is 1.85 x 10 J. While What is the potential difference between the capacitor plates? the capacitor is kept connected to the power supply, a slab of dielectric is inserted that completely fills the space Express your answer with the appropriate units. between the plates. This increases the stored energy by 2.52 x 10- J. ? For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Energy storage with and without a dielectric.
