Describe what is meant by an electric field
WebWhere: E = electric field strength (N C-1); F = electrostatic force on the charge (N) Q = charge (C) It is important to use a positive test charge in this definition, as this determines the direction of the electric field; The electric field strength is a vector quantity, it is always directed:. Away from a positive charge; Towards a negative charge; Recall that opposite … WebIf an electric field is defined as the force per unit charge, then by analogy an electric potential can be thought of as the potential energy per unit charge. Therefore, the work done in moving a unit charge from one point …
