Electric Field Due to Point Charge Calculator & Formula

The electric field produced by a point charge is the starting point of Electrostatics and forms the foundation for many advanced problems in Electromagnetics. In GATE exam, questions based on point charges often test a student’s understanding of inverse square law behavior and correct substitution of physical constants.

Electric Field Due to Point Charge Calculator

Inputs Clear Input

Point Charge in nano coloumb (input1) :

Distance from point charge in meters (input2) :

Outputs Calculate

Electric Field in V/m (output1) :

EXAMPLE:

INPUTS:

• Charge (q) = 5 nColoumb
• Distance (d) = 0.2 meters

OUTPUT:

• Electric field (E) = 1123.46 V/m

Electric Field Point Charge Formula

Where,

E = Electric Field Strength ( Newtons per coulomb, N/C) q = Magnitude of Point Charge (Coulombs, C) r = Distance from the point charge to the point where field is to be measured (Meters, m)

Summary: This calculator instantly computes electric field intensity for any given charge and distance, allowing students to verify answers, practice numericals quickly, and focus on conceptual clarity rather than arithmetic.
