A circuit to verify Ohm's law uses an ammeter and a voltmeter, connected correctly to the resistor in series or parallel. In the circuit:
Answer: (C) The ammeter is always connected in series and the voltmeter in parallel
The ammeter must carry the same current as the resistor, so it is placed in series with it. The voltmeter must measure the potential difference across the resistor, so it is placed in parallel with it.
