Electric Field
The electric field acts as a shortcut for calculating the electric force on a test charge , similar to how the gravitational field simplifies calculations for gravitational force. Instead of recalculating the force based on Coulomb's Law (and adding the forces of multiple source charges), we can use the electric field, where:
In the same way that gives the gravitational force per kilogram, gives the electric force per coulomb.
