How are ammeters and voltmeters connected in a circuit? What do they help us measure?
(N/A) An ammeter is always connected in series with the circuit components. It measures the electric current flowing through the circuit.
$A$ voltmeter is always connected in parallel across the points between which the potential difference is to be measured. It measures the potential difference across a conductor.
