  • A shunt of resistance  is connected across a galvanometer of <img alt="120\Omega" src="https://en

A shunt of resistance 1\Omega is connected across a galvanometer of 120\Omega resistance. A current of 5.5 ampere gives full scale deflection in the galvanometer. The current that will give full scale deflection in the absence of the shunt is nearly:

Option: 1

5.5 ampere


Option: 2

0.5 ampere


Option: 3

0.004 ampere


Option: 4

0.045 ampere

 The current that will give full-scale deflection in the absence of the shunt is nearly equal to the current through the galvanometer when the shunt is connected i.e Ig.

\begin{aligned} & \text { As } I_g=\frac{I S}{G+S} \\ & =\frac{5.5 \times 1}{120+1}=0.045 \text { ampere. } \end{aligned}
