A circuit to verify Ohm's law uses ammeter and voltmeter in series or parallel connected correctly to the resistor. In the circuit

Asked in JEE Main 6th Sept 2nd Shift 2020 · Ammeters and voltmeters in circuits

Answer: (3) ammeter is always connected in series and voltmeter in parallel

Step-by-step solution

An ammeter must carry the same current as the resistor, so it goes in series.

A voltmeter must see the same potential difference as the resistor, so it goes in parallel.

So the ammeter is in series and the voltmeter is in parallel.

Why the other options are wrong
