A galvanometer of resistance 98 ohms is shunted by a resistance of 2 ohms. The fraction of the total current that pass through is.

Options

A. `1//50`
B. `1//49`
C. `1//2`
D. `1//98`

Answer

A

Explanation

Fraction of current passing thorught galvanometer is give by
`rArr (I_(g))/(l) = (S)/(S+G) = (2)/(2+98) = (2)/(100)`
or `(l_(g))/(l) = (1)/(50)`
