Question

verify ohm's law with an experiment?​

Answer 1

Explanation:

The voltmeter (V) measures the potential difference across the ends of the resistance wire (R). As the key (K) is closed, current flows in the circuit. The rheostat (Rh) is adjusted to get the minimum (non-zero) reading in the ammeter (A) and voltmeter (V). The ammeter and voltmeter readings of current (I) are noted.
