What is the relation between electric field and voltage?
What is the relation between electric field and voltage? Work and Voltage: Constant Electric Field 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. What causes electric force? Electrical forces […]
