Question

1. To determine the equivalent resistance of two resistors when connected in series, a student arranged the circuit components as shown in the diagram. But he did not succeed to achieve the objective.
Which of the following mistakes he has committed in setting up the circuit? (a) Position of ammeter is incorrect
(b) Position of voltmeter is incorrect
(c) Terminals of ammeter are wrongly connected
(d) Terminals of voltmeter are wrongly connected

Answer 1

Answer:

d

Explanation:

terminals of voltameter are wrongly connected

Answer 2

(c) Terminals of ammeter are wrongly connected

The ammeter here would be used to measure the current passing through the wire with the resistances in series. However the terminals of ammeter are wrongly connected. The positive terminal of ammeter must be connected to the positive terminal of the battery, and negative with the negative.

Hope it helps
