B8: Capacitors, Dielectrics, and Energy in Capacitors
(V) is the electric potential difference (Delta varphi) between the conductors. It is known as the voltage of the capacitor. It is also known as the voltage across the capacitor. A two-conductor capacitor plays an important role as a component in electric circuits. The simplest kind of capacitor is the parallel-plate capacitor.

Contactors K3-..K are suitable for switching low-inductive and low loss capacitors in capacitor banks (IEC 70 and 831, VDE 0560) without and with reactors. Capacitor switching contactors are fitted with early make contacts and damping resistors, to reduce the value of making current 70 x Ie.
Understanding Capacitors
In series combination, the same electrical current flows through each capacitor and the applied voltage V is divided across each capacitor. Due to external applied voltage each of the capacitors acquires an identical charge Q. The sum of the capacitor voltages must equal the source voltage (Kirchhoff''s voltage law) V = V 1 + V 2 + V 3

Understanding the Different Types of Capacitors
For precision circuits, you''ll want a capacitor with a low tolerance. Voltage Rating. This is a big one. The voltage rating tells you the maximum voltage the capacitor can handle. It''s like the speed limit for a capacitor. If you exceed this limit, you risk damaging the capacitor or even causing it to fail catastrophically.

6.1.2: Capacitance and Capacitors
The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.
