Electric field due to circular loop of charge

Electric field

The space around a charged particle in which another charge experience a force is known as electric field.
The source of electric field is either a charge or a time varying magnetic field.
If the value of electric field does not change with time, then it will be uniform electric field, otherwise it will be non-uniform electric field.

Electric field due to circular loop of charge

If λ is linear charge density, then the charge on dl
dq = λ dl ⇒ dq = (q / 2πa) dl
Electric field at P due to charge dq

$https://latex.codecogs.com/svg.image?dE = |d\overrightarrow{E}|=\frac{kdq}{(CP)^{2}}$

Special cases

When P lies at the centre of the loop i. e., r = 0, then E = 0
When P lies very far from the centre of the loop i. e., r >> a, then E = kq / r²
In this case circular loop behaves as a point charge.
