8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. 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. ...
8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of …

Force Between the Plates of a Plane Parallel Plate Capacitor
capacitor
So the peak resistor voltage is about 10 volts, the peak capacitor voltage is about 2.9 volts, and the phase difference between the two voltages is exactly 90 degrees. The reason for the phase difference is that the capacitor voltage is always 90 …
Why does the distance between the plates of a …
As you move the plates closer at the same applied voltage, the E field between them (Volts per meter) increases (Volts is the same, meters gets smaller). This stronger E field can hold more charges on the …
Basics of Capacitance
Capacitors In Series When capacitors are connected in series, as shown in Figure 1, the effect is the same as adding the distances between the plates of each capacitor. The total distance between the plates is greater. Therefore, the total capacitance is less.
19.5 Capacitors and Dielectrics
A system composed of two identical, parallel conducting plates separated by a distance, as in Figure 19.14, is called a parallel plate capacitor is easy to see the relationship between the voltage and the stored charge for a parallel plate capacitor, as shown in Figure 19.14..
Why changing the distance between two parallel plates capacitor …
Or, to put it another way, it requires more work per unit charge (more voltage) to separate the charge the greater the distance between the plates. I am still confused than what does is it mean when the value of 𝑄 is decrease /increase while changing the distance between plates. and when you say the net charge is constant is it …
5.16: Potential Field Within a Parallel Plate Capacitor
Note that the above result is dimensionally correct and confirms that the potential deep inside a "thin" parallel plate capacitor changes linearly with distance between the plates. Further, you should find that application of the equation ({bf E} = - nabla V) (Section 5.14) to the solution above yields the expected result for the electric field intensity: ({bf E} …

Capacitor Specifications: what they mean
There is a link between the margin provided between the actual voltage at which the capacitor is run and its rated operating voltage. The greater the margin, the higher the reliability. Often commercial design guidelines stipulate that capacitors should not be run above 50% of their rated values, and guidelines for designing high reliability …
voltage
If the capacitance is greater, I assume either the area of the capacitor plates is larger or the distance between the plates is smaller. Intuitively, how does the "larger areas" and the "smaller distance between the plates" affect the electrons'' movement and the charge so that it manifests on charging velocity?
