ELECTRICFIELD

Dear Suluguri

An electric field surrounds electrically charged particles and time-varying magnetic fields. This electric field exerts a force on other electrically charged objects. Michael Faraday introduced the concept of an electric field.

The electric field is a vector field with SI units of newtons per coulomb (N C⁻¹) or, equivalently, volts per metre (V m⁻¹). The SI base units of the electric field are kg·m·s⁻³·A⁻¹. The strength or magnitude of the field at a given point is defined as the force that would be exerted on a positive test charge of 1 coulomb placed at that point; the direction of the field is given by the direction of that force. Electric fields contain electrical energy with energy density proportional to the square of the field amplitude. The electric field is to charge as gravitational acceleration is to mass and force density is to volume.

All the best.
