How to measure electric potential

WebThe electric potential is the electric potential energy of a test charge divided by its charge for every location in space. Because it's derived from an energy, it's a scalar field. These two fields are related. The electric field and electric potential are related by displacement. Field times displacement is potential… Ed = ∆ V WebThe ampere: a measure of electrical current, which is the rate of flow of charge. When an ammeter is used to measure the size of an electric current, the reading from the meter is in units of ampere. Connect the ammeter into the circuit in series so that there is no branching: the current in the wires will be the same as that in the ammeter.
