Under which condition Electric intensity at a point is zero but electric potential is not zero. And Electric potential at a point is zero but electric intensity is not zero..
Answers
Electric field is a Force and potential or voltage is the energy required to overcome this force or the energy required to move a particle from one position to other .
- When electrical field is zero, the energy required to overcome it will also be zero.
- When a particle is to be moved from a point, say A to a point, say B such that the electric field intensity at A is equal to that at B, the net change in electric field experienced by the particle is zero, but the energy required to move the particle from A to B is not zero, so V is not equal to zero
So, according to the equation
E = gradient(V),
When E is zero, V may or may not be zero. But if V is zero, E will definitely be zero
Answer:
Electric Potential is zero at a particular point, it does not necessarily mean that the electric Field is also zero at that point. It can be understood with the Case of Electric Dipole.
we have a positive and a negative charge of equal magnitude separated by a certain distance , then the electric potential at the mid point of the path is 0 but the electric field intensity is non zero there. Remember electric potential is a scalar quantity but electric field intensity is a vector quantity.
