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.
a) What is the magnitude of the electrical field in the capacitor ?
b) 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.
c) What is the electrical potential between point A and B ? Given that the shared area of the parallel plates is 4500 cm^2.
d) What is the capacitance of this parallel plate capacitor ?
