Which of the following circuits is correct for verification of Ohm's law?

Step-by-step solution

To verify Ohm's law, we need to measure the current flowing through a resistor and the potential difference across it. 1. An ammeter measures current and must be connected in series with the resistor. 2. A voltmeter measures potential difference and must be connected in parallel across the resistor. 3. The polarities of both instruments must be correct: the positive terminal of the ammeter and voltmeter should be connected towards the positive terminal of the battery (higher potential).
