A parallel-plate capacitor (Homework #2) A parallel-plate capacitor is made by a pair of plates with area A and separation d. At first, the plates are charged up to +Q and -O respectively, and then a battery is disconnected. Express all the answers for a) through f) only by Q, d, A and 5 +Q 2d -Q Area A a) What is the electric field E inside of the capacitor? b) What is the potential difference V between the plates?...
Uncharged parallel-plate capacitor
If an uncharged parallel-plate capacitor (capacitance C) is connected to a battery, one plate becomes negatively charged as electrons move to the plate face (areaA). In the figure below, the depth d from which the electrons come in the plate in a particular capacitor is plotted against a range of values for the potentialdifference V of the battery. The vertical scale is set by ds = 3.50 pm, and the horizontal scale is set by Vs = 40.0 V. What...
