उत्तर
An ammeter of resistance R gives a full-scale deflection when a current of 2 A passes through it. If it is measured with a maximum current of 10 A, the required shunt is `underlinebb("R"/4)`.
Explanation:
Given, l = 2A, lmax = 10A
Since, shunt resistance, S = `(lR)/(l_"max" - l)`
= `(2R)/(10 - 2) = 2/8R = 1/4R`
