Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 31: Capacitor

Capacitance

Capacitance refers to the ratio of the variation in the electric charge of a system to the consistent change in its electric potential. There are two closely related concepts of capacitance including self-capacitance and mutual capacitance. A body that can be electrically charged shows self-capacitance.

Energy Stored in a Capacitor

Energy stored in a capacitor is defined as the electrical potential energy, and it is thus associated with the charge Q and voltage V on the capacitor. We must be careful when relating the equation for electrical potential energy i.e. ΔPE = qΔV to a capacitor. Think of that ΔPE is the potential energy of a charge ‘q’ going through a voltage ΔV.

Electric Field due to Charge ‘q’

To calculate the electric field E at a point P due to a gathering of charges, we can bring a small positive charge ‘q’ to the point ‘P’ and calculate the force on this test charge. The electric field formed by Q is given by:

E = (keQ/r2)

If Q is positive, then the electric field points outward away from the charge.

Corona Discharge

An electrical release transported on by the ionization of a liquid such as air surrounding a conductor that is electrically charged is known as corona discharge. Impulsive corona discharges happen certainly in high-voltage systems unless care is taken to bind the electric field strength.

High-voltage Generator

The shock absorber is a portion of the suspension system. The high-voltage generator pushes a power transistor based on self-excited oscillation, which transforms dc to ac. A high-frequency transformer with a high turns ratio is used to raise the voltage. In addition, the structure uses the car battery as a dc power supply.

Dielectrics

Dielectric refers to an insulating substance or a very poor conductor of electric current. When these dielectrics are found in an electric field, usually no current drifts in them because, unlike metals, they have no lightly bound, or free, electrons that may float through the substance. In its place, electric polarization happens.

Isolated Capacitor

An isolated capacitor is described as a capacitor on its own i.e. it is not associated in the circuit such that it cannot be charged or discharged.
