Question 346 of 380

Consider a galvanometer shunted with 5Ω5\Omega resistance and 22% of current passes through it. What is the resistance of the given galvanometer?

Show answer and solution

Answer: (A) 245Ω245\Omega

IG=2100×I{I}_{G}=\dfrac{2}{100}\times I (Given)
0.98I×5=0.02×RG0.98I\times 5=0.02\times {R}_{G}
RG=245Ω{R}_{G}=245\Omega
