Consider an infinite parallel-plate capacitor, with the lower plate (at z = −d/2) carrying surface charge density −σ, and the upper plate (at z = +d/2) carrying charge density +σ. ... Of course, there must be mechanical forces holding the plates apart—perhaps the capacitor is filled with insulating material under pressure. Suppose we ...
The capacitance of a capacitor is a parameter that tells us how much charge can be stored in the capacitor per unit potential difference between its plates. Capacitance of a system of conductors depends only on the geometry of their …

Note also that the dielectric constant for air is very close to 1, so that air-filled capacitors act much like those with vacuum between their plates except that the air can become conductive if the electric field strength becomes too great. …
The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates. In other words, capacitance is the largest amount of charge per volt …

A word about signs: The higher potential is always on the plate of the capacitor that has the positive charge. Note that Equation ref{17.1} is valid only for a parallel plate capacitor. Capacitors come in many different geometries and the formula for the capacitance of a capacitor with a different geometry will differ from this equation.
This implies that for capacitors of lower capacitances you need more potential to store the same amount of charge, what your TA did was reduce the capacitance of the system so now to hold the same amount of charge the potential increases. ...

The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from ...
