Question

A moving coil galvanometer gives a full scale
deflection of 30 when connected in a circuit. When
a resistance of 20 is connected in parallel with the
galvanometer the deflection of the galvanometer
reduces to 20. What is the resistance of the
galvanometer :
(1) 10 (2) 20 (3) 30 (4) 40

explain it properly plz​

Answer 1

Answer:

I think 20 is correct answer.....I hope help you.......
