Capacitance refers to the ability of a device known as a capacitor, to store electrical energy in an electric field. Essentially, it is an electrical component consisting of two parallel conductors (metal plates) separated by a dielectric material. Capacitors are widely used in electronics to add capacitance to a circuit.
When a voltage source is connected to a capacitor, the capacitor plates charge. One plate becomes positively charged, and the other plate becomes negatively charged. The electrical energy is stored in the form of electrical charges that create a potential difference, similar to a small rechargeable battery.
There is some capacitance between two closely spaced electrical conductors in a circuit, but a capacitor is specially designed to add capacitance to a circuit. Originally a capacitor was called a “condenser” or “capacitor,” terms that are still widely used in many languages – but not in English, except for condenser microphones, also known as capacitor microphones.
A vacuum can be used to separate the conductors as well; this type of capacitor is called a “vacuum capacitor.” Capacitance is an important concept in electronics and is used in a variety of applications in electronic circuits.
