Properties Of Conductors In Electric Field Properties Of Conductors In Electric Field :- When a conductor is placed in an electric field, it exhibits several distinct behaviors due to the free movement of charge within it. Below are the key properties of conductors in an electric field : 1. Free Charges (Electrons) Move Easily…
Self Energy | Self Energy Of A Charged Body Self Energy | Self Energy Of A Charged Body :- The self energy of a charged body refers to the amount of work required to charge the body by bringing in infinitesimal elements of charge from infinity and distributing them to form the complete charged…
Energy Density Of Electric Field Energy Density Of Electric Field :- Consider a small body of mass m and charge q placed in an electric field E. When released, it accelerates in the direction of the field due to the force qE, gaining kinetic energy. This energy comes from the electric field, indicating that…
Electrostatic Pressure Electrostatic Pressure :- Electrostatic pressure describes the mechanical force per unit area exerted by an electric field on a charged surface. It arises due to the mutual repulsion of like charges distributed over the surface of a body. When electric charges accumulate on a conductor, they repel each other due to the electrostatic…
Equipotential Surfaces | What Are Equipotential Surfaces Equipotential Surfaces | What Are Equipotential Surfaces :- In the following figure if a charge is shifted from point A to B on a surface M which is perpendicular to the direction of electric field, then no work is done because electrostatic force on the charge particle…

Electric Potential At The Edge Of A Disc Electric Potential At The Edge Of A Disc :- Let us calculate the electric potential at the edge of a disc of radius R, which is uniformly charged and has a surface charge density σ. Let A be the point on the diameter AB at the…
Potential Difference Potential Difference :- Potential difference between two points in an electric field is defined as the work done by an external force per unit positive charge in moving it from one point to another against the electric field without acceleration. It is a scalar quantity and is measured in volts (V). Let the…
Electric Potential Electric Potential :- Electric potential, often denoted as V, is the amount of electric potential energy per unit charge at a point in an electric field. In simpler terms, it tells us how much work is needed to move a unit positive charge from a reference point (usually infinity) to a specific…
Electric Potential Due To A Charged Sphere Electric Potential Due To A Charged Sphere :- We will derive the electric potential due to : A conducting sphere (solid or hollow) (all charge on the surface) A uniformly charged non-conducting sphere (charge distributed uniformly inside the volume of the sphere) Each case will be analyzed…
