Factors Affecting Capacitance
PLATE SPACING: All other factors being equal, further plate spacing gives less capacitance; closer plate spacing gives greater capacitance. Explanation: Closer spacing results in a greater field force (voltage across the capacitor divided by the distance between the plates), which results in a greater field flux (charge collected on the plates) …
13.3: Factors Affecting Capacitance
There are three basic factors of capacitor construction determining the amount of capacitance created. These factors all dictate capacitance by affecting how much electric field flux (relative difference of electrons between plates) will develop for a given amount of electric field force (voltage between the two plates):
Understanding voltage rating of a capacitor
The dielectric of a capacitor breaks down if the voltage is applied across it, this is known as electrical breakdown. Also arcing will occur between the capacitor plates resulting in a short-circuit. The working voltage of a capacitor depends on the type and thickness of the dielectric material employed.

Fundamentals | Capacitor Guide
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.

6.1.2: 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 multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

The purpose of this paper is to show how voltage distortion may cause accelerated aging of insulation systems, particularly of self-healing capacitors. Distortion is due to the presence, in the supply voltage waveform, of harmonics which are typically detected in distribution ac networks. These harmonics sum up to the fundamental component giving rise to voltage …
