A uniform electrical field is established by connecting the plates of a parallel-plate capacitor to a 11V battery. The plates of the capacitor are separated a distance 3.50 cm. What is the magnitude of the electrical field in the capacitor ? A positive charge of 6.0 x10^-6 C moves from the positive to the negative plate. What is the change in electrical potential energy for this charge Points A and B in the figure above are 0.80 cm apart. What is the electrical potential between point A and B ? Given that the shared area of the parallel plates is 4500 cm^2. What is the capacitance of this parallel plate capacitor?
