The Work Per Unit Charge Required To Move A Charge Between Two Points In An Electric Circuit Defines Electric. We’ve seen earlier that the line integral of the field is the negative of the potential difference between the two endpoints. The electric field is by definition the force per unit charge, so that multiplying the field times the plate separation gives the work per unit charge, which is by definition the change in voltage.
So, in other words, the potential difference between two points is. The electric field is by definition the force per unit charge, so that multiplying the field times the plate separation gives the work per unit charge, which is by definition the change in voltage. We’ve seen earlier that the line integral of the field is the negative of the potential difference between the two endpoints.
