SUMMARY
The Electric Field (E-field) is defined as the force per unit charge, represented mathematically as \(\vec E \equiv \mathop {\lim }\limits_{q_0 \to 0} \frac{{\vec F}}{{q_0 }}\), where \(\vec F\) is the electric force and \(q_0\) is a test charge. It is not a force itself but rather a field that generates a force on charged objects within its vicinity. The E-field is often referred to as a "force field" due to its ability to exert forces on other charges, but it fundamentally represents an effect produced by electric charges. This distinction is crucial for understanding electromagnetic interactions.
