A circuit to verify Ohm's law uses ammeter and voltmeter in series or parallel connected correctly to the resistor. In the circuit: (a) Ammeter is always connected in series and voltmeter in parallel (b) Both ammeter and voltmeter must be connected in series (c) Both ammeter and voltmeter must be connected in parallel (d) Ammeter is always used in parallel and voltmeter is series

Answer: (a). Ammeter must carry the same current as the resistor, so it is in series (low resistance). Voltmeter must have the same p.d. as the resistor, so it is in parallel (high resistance). So the answer is (a).

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

Show answer and solution

Answer: (a)

Ammeter must carry the same current as the resistor, so it is in series (low resistance).
Voltmeter must have the same p.d. as the resistor, so it is in parallel (high resistance).
So the answer is (a).
