Capacitive Voltage Divider Circuit as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts. As the two capacitors are in series, the charge Q on them is the same, but the voltage across them will be different and related to their capacitance values, as V = Q/C.. Voltage divider circuits may be constructed from reactive components just as easily as …

What is the working principle of a capacitor?
The ability of the capacitor to store charges is known as capacitance. Equation of capacitance is given by, q = C V [q = c h a r g e, C = c a p a c i tan c e, V = v o l t a g e] Working principle of a capacitor: Consider the following circuit, which shows the working principle of a parallel plate capacitor with a dielectric between them.
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.

0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of separation because the smaller the value of d, the …
