# Electric Field Strength Calculator

## The online calculator of the electric field strength with a step-by-step solution helps you calculate the electric field strength E if the charge q and the force F acting on a given charge are known, and also the electric field strength E if the charge q and the distance r from the given charge are known. Units of measurement can include any Si prefix. The calculator automatically converts one unit to another and gives a detailed solution. The calculator calculates: The strength of the electric field by charge and the force acting on a given charge.The strength of the electric field by charge and distance from a given charge.

Electric Field Strength E if Known: Charge q and Force F Acting on a Given Charge.

The strength of the electric field E at some point is the ratio of the force acting on the charge placed at this point to the charge. Based on the formula, the electric field strength is numerically equal to the force if the charge q is equal to one. The SI unit of electric field strength is - Volt (V).
Force F =
Charge q =
The SI unit of E

Electric Field Strength E if Known: Charge q and Distance From Charge r.

If the electric field is created by a single point charge q, then the strength of such a field at a point spaced at a distance r from the charge is equal to the product of q and k - electrostatic constant k = 8.9875517873681764 × 109 divided by r2 the distance squared.
The SI unit of electric field strength is - Volt (V).
