Two galvanometer A and B require the current of 4 mA and 7mA repectively to produce the same deflection of 20 divisions. Then

A

A is less sensitive than B

B

`A is more sensitive than B

C

Both A and B are equally sensitive

D

sensitive of B is 7/4 times that of A

Text Solution

Verified by Experts

The correct Answer is:
