Question

What is capacitor and capacitance?

Answer 1

Capacitor:

1. A capacitor is a two-terminal electrical device that possesses the ability to store energy in the form of an electric charge.
2. Capacitors store energy by holding apart pairs of opposite charges.
3. In an electric field capacitor is a device used for storing electrical energy.
4. The capacitor has two terminals and it is a passive component.
   

Capacitance:

1. The effect caused by a capacitor is called capacitance.
2. $\mathrm{Charge}=\mathrm{capacitance}\times \mathrm{voltage}$
3. In an electrical circuit, there is always a capacitance between two electrical conductors that are close to one another.
4. One of the important applications of capacitors is the conditioning of power supplies.
5. Devices using Dynamic Random Access Memory (DRAM) use capacitors to represent binary data as bits.
6. The SI unit of capacitance is $\mathrm{Farad}$
