Assertion (A): A high resistance is connected in series with the galvanometer of Meter Bridge. |
Reason (R): As resistance increases, the current also increases. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: C
Solution :
Option [c] is correct |
Explanation: 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 Ohms law, I = V/R. So as resistance increases, the current decreases. Hence the reason is false. |
