Question

To find the equivalent resistance of two resistors connected in series, the connection of ammeter is correct in the circuit:

(a) Circuit A
(b) Circuit B
(c) Both the circuits
(d) Neither of the two circuits.

Answer 1

Inorder to find the resistance of the two resistors connected in series, the ammeter should also be connected in series with the circuit, and positive terminal of the ammeter should be connected to the positive terminal of the battery.
Therefore, both the circuits are correct.
