Question
A $50\, ohm$ galvanometer gets full scale deflection when a current of $0.01\, A$ passes through the coil. When it is converted to a $10\, A$ ammeter, the shunt resistance is ........... $\Omega $
✓

Answer

(b) ${i_g} = i\frac{S}{{G + S}}$

$ \Rightarrow $$\frac{{0.01}}{{10}} = \frac{5}{{50 + S}}$

$ \Rightarrow $ $S = \frac{{50}}{{999}} = 0.05\,\Omega $.

A thin rod having a length of $1\; m$ and area of cross-section $3 \times 10^{-6}\,m ^2$ is suspended vertically from one end. The rod is cooled from $210^{\circ}\,C$ to $160^{\circ}\,C$. After cooling, a mass $M$ is attached at the lower end of the rod such that the length of rod again becomes $1\,m$. Young's modulus and coefficient of linear expansion of the rod are $2 \times 10^{11} Nm ^{-2}$ and $2 \times 10^{-5} K ^{-1}$, respectively.
