Question

Explain with the help of a labelled circuit diagram how you will find the resistance of a combination of
three resistors, or resistance R1, R2, R3, joined in parallel. Also mention how you will connect the ammeter
and the voltmeter in the circuit when measuring the current in the circuit and the potential difference
across one of the three resistors of the combination.

Answer 1

ammeter is connected in series and voltmeter is connected in parallel

Answer 2

Answer:

The diagram for the resistors connected in parallel will be as in diagram.

Here the voltmeter will be connected to the all three resistors in parallel as the potential will be same for resistors connected in parallel, and the ammeter will be connected in series with the all three resistors when combined as the current will be same in series combination. As the ammeter will measure the amount of current flowing in the circuit and the voltmeter will measure the potential difference applied in the circuit.
