A circuit to verify Ohm's law uses ammeter and voltmeter in series or parallel connected corrected correctly to the resistor. In the circuit :
ammeter is always used in parallel and voltmeter is series
Both ammeter and voltmeter must be connected in parallel
ammeter is always connected in series and voltmeter in parallel
Both ammeter and voltmeter must be connected in series
Solution
Since the potential difference is measured across the two ends of the component, the voltmeter must always be connected in parallel to the components. An ammeter is an instrument which is used to measure the amount of current flowing in the circuit or through any component. It also consists of two terminals. The current is measured at a point. Therefore, the ammeter must be connected in series with the circuit components.Ohm’s law states that voltage (potential difference) across a resistance in a circuit is directly proportional to the current flowing through it.Therefore, in Ohm’s law voltmeter is connected in parallel to the resistor and ammeter is connected in series.
