Question

Write details of procedure and formula for measurement of electric field and potential?

Answer 1

Electric field

Electric field is the space surrounding a charge where another charge can experience a force is called electric field.

Intensity of Electric field / electric field at any point

Intensity of Electric field / electric field at any point is the force experienced by unit positive charge(test charge) placed at that point.

the force on a charge q kept at a point where the electric field is E is given by F =qE

eElectric field E = F/q

Electric potential

The electric potential at a point in an electric field is the work done in carring a test charge of unit msgnitude from infinity to that point.

electric potential V = $V=\int_{\infty }^{r} E.dx$ E is the Electric field and dx is the displacement
