Is an a reason of constant potential electric field is zero?

Is an a reason of constant potential electric field is zero?

In a region of constant potential (V = constant) , E=-dVdr=0, i.e., electric field is zero. As E=0, there can be no charge inside the region. Choices (b) and (c ) are correct.

Which of the following statement is correct in a region of constant potential?

Which of the following option is incorrect in a region of constant potential?

Complete answer: The electric field will be uniform in the given region if and only if there is linear change in potential with the distance x. Since the potential does not change. The electric field cannot be uniform. Therefore, the option (A) is incorrect.

What is constant potential?

A constant-potential (CP) charging source implies that the charger maintains a constant voltage independent of the charge current load. Vented nickel-cadmium and lead-acid batteries exhibit a pronounced voltage increase in response to an applied constant current as the battery approaches full charge.

What is importance of equipotential surface?

Some important properties of equipotential surfaces : Work done in moving a charge over an equipotential surface is zero. The electric field is always perpendicular to an equipotential surface. The spacing between equipotential surfaces enables us to identify regions of strong and weak fields.

Why is equipotential important?

Equipotential lines provide a quantitative way of viewing the electric potential in two dimensions. Every point on a given line is at the same potential. Such maps can be thought as topographic maps.

Why are equipotential lines circles?

Equipotential lines: point charge so that the radius r determines the potential. The equipotential lines are therefore circles and a sphere centered on the charge is an equipotential surface.

Why electric field is always perpendicular to equipotential surface?

Equipotential surfaces have equal potentials everywhere on them. For stronger fields, equipotential surfaces are closer to each other! These equipotential surfaces are always perpendicular to the electric field direction, at every point.

Why electric field is always perpendicular to a uniformly charged spherical shell?

The charges produce an electric field outside the conductor. On the surface of conductors in electrostatic equilibrium, the electric field is always perpendicular to the surface. Why? Because if not, charges on the surface of the conductors would move with the electric field.

What is electric field due to spherical shell?

So, the electric field inside a hollow sphere is zero.
