In the setup used for verifying Ohm's law, the instrument that must be connected across the conductor whose resistance is being studied is the
Aammeter
Bvoltmeter
Crheostat
Dkey
Answer & Solution
Correct answer: B. voltmeter
To measure the potential difference across the conductor, a voltmeter is connected in parallel across it. An ammeter is connected in series to measure the current through the conductor.
