Electric Potential Due To Multiple Charges Electric Potential Due To Multiple Charges :- Electric potential is a scalar quantity that describes the potential energy per unit charge at a point in an electric field. When dealing with multiple point charges, the total electric potential at a given point in space is the algebraic sum…
Electric Potential Due To A Point Charge Electric Potential Due To A Point Charge :- Let us consider a point charge +Q placed at a fixed point O in space. We want to calculate the electric potential V at a point a P located at a distance r from this charge. By definition, electric potential…
Electrostatic Forces Are Conservative Electrostatic Forces Are Conservative :- Conservative force are those force in which work done by the force or against the force does not depend on the path followed but only depends on the initial and final positions. In other words the work done in closed path is zero. To prove…
Electrostatic Potential Electrostatic Potential :- Before discussing electrostatic potential at a point, first we define electric potential difference because only differences in potential can be measured directly, not the absolute potential itself. The reason for that is : Electric Potential, just like gravitational potential, is relative. We need a reference point (usually taken at…
Electrostatic Potential Energy Electrostatic Potential Energy :- Just like gravitational potential energy of a mass in a gravitational field, we can derive an expression for electrostatic potential energy of a charge in an electric field. Let us assume that a charge +Q is placed at the origin which produces electric field . Let a…
