Electric Field

An Electric field can be considered an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. Electric fields are usually caused by varying magnetic fields or electric charges. Electric field strength is measured in the SI unit volt per metre (V/m).

What Is an Electric Field?

An electric field is defined mathematically as a vector field that can be associated with each point in space, the force per unit charge exerted on a positive test charge at rest at that point.

The formula of the electric field is given as,

E = F /Q

Where,

E is the electric field.
F is the force.
Q is the charge.

The direction of the field is taken as the direction of the force which is exerted on the positive charge. The electric field is radially outwards from the positive charge and radially towards the negative point charge.

The electric field is generated by the electric charge or by time-varying magnetic fields. In the case of an atomic scale, the electric field is responsible for the attractive forces between the atomic nucleus and electrons which hold them together.

Frequently Asked Questions on Electric Field

Q1

What is an electric field?

The space surrounding an electric charge or a group of charges in which another charge experiences a force is called an electric field.

Q2

When is the electric field said to be uniform?

If the force on the test charge is said to be the same at all points in a field, both in magnitude and direction, then the field is said to be uniform.

Q3

When is the electric field said to be non-uniform?

If the force on the test charge varies from point to point in a field, then the field is said to be non-uniform.

Q4

Does a charge experience a force due to its own field?

No, a charge will not experience any force due to its own field.
