Solution


Q.

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.               [2023]

Assertion A: For measuring the potential difference across a resistance of 600Ω , the voltmeter with resistance 1000Ω will be preferred over voltmeter with resistance 4000Ω .

Reason R: Voltmeter with higher resistance will draw smaller current than voltmeter with lower resistance.

In the light of the above statements, choose the most appropriate answer from the options given below.
1 A is not correct but R is correct  
2 Both A and R are correct and R is the correct explanation of A  
3 Both A and R are correct but R is not the correct explanation of A  
4 A is correct but R is not correct  

Ans.

(1)

Error of voltmeter decreases with increase in its resistance.
