Directions : In the following questions, A statement of Assertion (A)...
Resistance of galvanometer is low. So, to protect it from damage a high resistance is connected in series with it which limits the flow of current through it. So the assertion is true. From Ohm's law, I = V/R. So as resistance increases, the current decreases. Hence the reason is false.

Directions : In the following questions, A statement of Assertion (A)...
Assertion (A): A high resistance is connected in series with the galvanometer of the meter bridge.
Reason (R): As resistance increases, the current also increases.
The correct answer is option C, i.e., A is true but R is false.
Explanation:
The meter bridge is a device used to measure the unknown resistance value of a given conductor. It consists of a long wire AB, a galvanometer G, a jockey J, and a resistance box R. The galvanometer is connected in parallel with the resistance box, and a high resistance is connected in series with the galvanometer.
Reasoning:
The galvanometer is a sensitive instrument that is used to measure small amounts of current. When a current passes through the galvanometer, a deflection is observed on the scale. In order to measure the unknown resistance accurately, the galvanometer should not carry a significant amount of current. Hence, a high resistance is connected in series with the galvanometer to limit the current passing through it.
Assertion:
A high resistance is connected in series with the galvanometer of the meter bridge.
The purpose of connecting a high resistance in series with the galvanometer is to limit the current passing through the galvanometer.
Reason:
As resistance increases, the current also increases.
This reason is incorrect. According to Ohm's Law, the current flowing through a circuit is inversely proportional to the resistance. As the resistance increases, the current decreases, and vice versa. Therefore, the reason given is false.
In conclusion, while the assertion is true, the reason provided is false. The resistance is connected in series with the galvanometer to limit the current passing through it, not to increase it.
Reason (R): As resistance increases, the current also increases.
The correct answer is option C, i.e., A is true but R is false.
