Question

the resistance of a coil of an ammeter is R.To increase its range four fold, the shunt resistance required is​

Answer 1

Answer:

Explanation:

Hey  

The resistance of the coil of an ammeter is R. The shunt required to increase its range n-fold should have a resistance is R/(n plus 1)

so here n=4 so answer is R/5

can you mark this as the brainlist answer please .. ^_^

Answer 2

Answer: N/3

Explanation:Bcz.. the formula for the shunt resistance to increase it's range N times (like here it is 4 times) is R/(N-1).

Where, R is the resistance of the coil of an ammeter.
