Electrostatic Potential And Capacitance Class 12 Notes Physics

A capacitor is a device that stores electric charge. Capacitance of a capacitor is the ratio of charge (Q) given and the potential (V) to which it is raised. C = (Q/V) Capacitance of a spherical conductor is C = 4πε 0 R, where R is the radius of the spherical conductor. The SI unit of capacitance is farad (F). Capacitance is a scalar quantity.

An electric field creates across the capacitor. The positive plate collects positive charges and negative plates collect negative charges from the battery. After a particular point, the capacitor holds the maximum amount of charge as per its capacitance with respect to the battery potential, This span of time is called as charging of the capacitor.

Electric Potential and Capacitance

The capacitance is an internist propriety of any configuration of two conductors when placed next to each others. The capacitor does not need to be charged (holding a charge Q with a potential difference ΔV across the conductors) for its capacitance to exist: also when a capacitor is not charged it does have a capacitance! An analogy is the

6 FAQs about [Capacitor capacitance notes recommendation]

What is the capacitance of a capacitor?

Electric & Magnetic Fields Capacitance 7.9 Capacitance The capacitor circuit symbol is two parallel lines The charge stored per unit potential difference (between the plates) A capacitor used in small circuits A parallel plate capacitor has a capacitance of 1 nF and is connected to a voltage supply of 0.3 kV. Calculate the charge on the plates.

What is the equivalent capacitance of n capacitors in parallel?

In other words, the equivalent capacitance of N capacitors in parallel is the sum of the individual capacitances. Considering the example of parallel plate capacitors, adding several in parallel is equivalent to extending the area of the plates. Since the capacitance is proportional to the area, it increases in direct proportion.

A simple capacitor can be made from two metal plates separated by an insulating material. The capacitance of the capacitor depends on the area of the plates, the distance between the plates and the permittivity of the dielectric material placed between the plates.
