What is meant by capacitance?

Capacitance is defined as the capacity of any material to store electric charge. The substance that stores the electric charge is called a capacitor, i.e. the ability of the capacitor to hold the electric charge is called capacitance.

What is a capacitance of a material?

It is denoted with the symbol C and is defined as the ratio of the electric charge stored inside a capacitor by the voltage applied. Thus, any material that has a tendency to store electric charge is called a capacitor and the ability of the material to hold electric charge is called the capacitance of the material.

What is the capacitance of a capacitor?

The capacitance of the majority of capacitors used in electronic circuits is generally several orders of magnitude smaller than the farad. The most common units of capacitance are the microfarad (μF), nanofarad (nF), picofarad (pF), and, in microcircuits, femtofarad (fF).

Is the capacitance of a capacitor fixed or variable?

The capacitance of any capacitor can be either fixed or variable, depending on its usage. From the equation, it may seem that ‘C’ depends on charge and voltage. Actually, it depends on the shape and size of the capacitor and also on the insulator used between the conducting plates.

What is the difference between a battery and a capacitor?

So the basic difference between the battery and the electric charge is that a battery stores the electric energy and releases it gradually over a long period of time but a capacitor almost instantaneously releases all its stored energy. A capacitor is sometimes also called a condenser and is an important part of a common electric circuit.

How does a capacitor store energy?

It consists of two electrical conductors that are separated by a distance. The space between the conductors may be filled by vacuum or with an insulating material known as a dielectric. The ability of the capacitor to store charges is known as capacitance. Capacitors store energy by holding apart pairs of opposite charges.

What is Capacitance
