MHT CET Physics question
A moving coil galvanometer gives full scale deflection when a current of 0.005 A is passed through its coil. It is converted into a voltmeter reading upto 5 V by using an external resistance of 975 . The resistance of the galvanometer coil is:
Answer: (B)
Solution
Total resistance , so ; 30, 40 and 50 do not fit. Hence the correct option is (b).
