The expression in Equation ref{8.10} for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference (V = q/C) between its plates.

Breakdown strength is measured in volts per unit distance, thus, the closer the plates, the less voltage the capacitor can withstand. For example, halving the plate distance doubles the capacitance but also halves its voltage rating. Table 8.2.2 lists the breakdown strengths of a variety of different dielectrics. Comparing the tables of Tables ...

The most common capacitor is known as a parallel-plate capacitor which involves two separate conductor plates separated from one another by a dielectric. Capacitance (C) can be calculated as a function of charge an object can store (q) and potential difference (V) between the two plates:

Question 4 (2 points) Suppose one of the plates of a parallel-plate capacitor was moved so that the area of overlap was reduced by half, but they are still parallel. How would this affect the capacitance? The capacitance would not change, even though the area of overlap decreases by a factor of 2. The capacitance would decrease by a factor of 2 ...
When the bottom plate moves under the influence of gravity, the overlapping area of the two plates of the parallel plate capacitor varies corresponding to a change in capacitance. The relation between the angle of tilt, overlapping area, and output capacitance is derived which is used to covert the output capacitance to the tilt angle.

6 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance …
