Electric Field Calculator
This electric field calculator calculates the electric field of an object based on the electric force which the object exerts and the amount of charge that the object has.
To use this calculator, a user just has to enter in the electric force, F, and the charge, Q, and then click the 'Submit' button, and the resultant answer will automatically be computed and shown. The electric force must be entered in in unit newtons (N). The charge of the object can be entered in picocoulombs, nanocoulombs, microcoulombs, millicoulombs, or coulombs, but will be converted to coulombs for calculation. The resultant answer, the electric field, will be calculated in unit N/C (newtons per coulomb).
The Electric field of a charge or charged item is directly proportional to the magnitude of the force and inverse proportional to the amount of charge that it contains. This means that the greater the magnitude of the force, the greater the electric field. Conversely the lesser the force, the smaller the electric field. Charge is the opposite. The greater the charge, the smaller the electric field. While, conversely, the smaller the charge, the greater the electric field.
Electric field is an important calculation in the field of electronics because electric fields exist in many types of circuit components. The most glaring example where electric
fields can be founds are capacitors. When charged a capacitor stores electric charge on its parallel plates (which is how they store charge). These charges, in turn, create an electric field,
emanating from the plates. Calculating the electric field quantitifies the magnitude of the electric field, which can be important and critical in different types of applications of electronic
circuits.
Example Calculation
If an object has an electric force, F, of 4N and a charge of 2C, what is the electric field of this object?
So based on the values of the parameters, we use the equation E=F/Q and substitute in the values into the equation.
E= 4N/2C= 2 N/C
