Question

A galvanometer has a resistance of 3663 $\omega$. A shunt S is connected across it such that 1/34 of the total current passes through the galvanometer. The combined resistance of the shunt and the galvanometer is

• A. 3665 $\omega$
• B. 111 $\omega$
• C. 107.7 $\omega$
• D. 3555.3 $\omega$

Answer 1

The correct option is C 107.7 $\omega$

$R_s=\frac{SG}{S+G}=\frac{111\times 3663}{111+3663}=107.7\omega$
