Question

The sensitivity of a galvarometer that measures
current is decreased by 1/40 times by using shunt
resistance of 10ohm.Then, the value of the resistance
of the galvanometer is?

Answer 1

Answer:

The sensitivity of a galvarometer that measures

current is decreased by 1/40 times by using shunt

resistance of 10ohm.Then, the value of the resistance

of the galvanometer is 390Ω

Explanation:

R=10 ohm

let the value of resistance of the galvanometer be r

Putting the values from the problem:

r =10(40−1)

= 390 Ω
