Potential of a conduction changes on charging:- What Is the ratio called?

Potential of a conduction changes on charging:- How is charge related to the potential?

What is potential at A?

Electric potential difference is the work , done to bring a unit +ve test charge from one point to another in an electric field:- What Is the relation between electric field and electric potential ?

Two charged conducting spheres of radii a and b are connected to each other by a wire. What is the ratio of electric fields at the surfaces of the two spheres? Use the result obtained to explain why charge density on the sharp and pointed ends of a conductor is higher than on its flatten portions.

A capacitor is charged to a certain potential and then allowed to discharges through a resistance R. The ratio of charge on the capacitor to current in the circuit.

Variation of field with distance of a charged conducting shell is given below. R is the radius of the sphere. Br Draw the potential-distance graph in the above case.

Conduction and are the two meth-ods of charging a body.
