WebApr 26, 2024 · To measure current in an electrical circuit we need to use a piece of electrical testing equipment. Clamp meters and ammeter can be used but in this example below we will be using a multimeter. The multimeter must be connected to the circuit so that the electrons can flow through it. WebTo measure the current flowing in a resistor or inductor or any components, the components should be disconnected and the ammeter should connect in series with that …
WebThe voltmeter is connected in parallel with the circuit to be measured. We do not want the voltmeter to load the circuit. Consequently an ideal voltmeter will have infinite resistance. An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit.
