Capacitance | CIE A Level Physics Revision Notes 2025

The capacitance of a capacitor is defined by the equation: Where: C = capacitance (F); Q = charge (C); V = potential difference (V); The unit of capacitance is the farad (F), where one farad is equivalent to one coulomb per volt. In practice, 1 F, or 1 C V –1, is a very large unit; As a result, capacitance values are often quoted in microfarads (μF), nanofarads

8.1 Capacitors and Capacitance

Capacitors are generally with two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum, and, in that case, a capacitor is then known as a "vacuum capacitor." However, the space is usually filled with an

6 FAQs about [Capacitor Research Notes]

What is a capacitor and how is It measured?

Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).

How does the mode of operation of a capacitor affect life and reliability?

Particular emphasis is given to the influence of the mode of operation of the capacitor upon life and reliability, including energy discharge, low- and high-frequency filtering in AC and DC systems, AC resonant inverters, and switch-mode power supply use, along with transient pulse filtering applications.

What factors affect the life of a capacitor?

The simplest example of a capacitor consists of two conducting plates of area A , which are parallel to each other, and separated by a distance d, as shown in Figure 5.1.2. Experiments show that the amount of charge Q stored in a capacitor is linearly proportional to ∆ V , the electric potential difference between the plates. Thus, we may write

What is the basic configuration of a capacitor?

Figure 5.1.1 Basic configuration of a capacitor. In the uncharged state, the charge on either one of the conductors in the capacitor is zero. During the charging process, a charge Q is moved from one conductor to the other one, giving one conductor a charge + Q , and the other one a charge − Q .
