Question
Consider the circuit shown. Galvanometer resistance is 10 Ω and current through galvanometer is 3 mA. Find the resistance of shunt.
Options :
10–3 Ω
7.5 × 10–3 Ω
6.75 × 10–3 Ω
3.75 × 10–3 Ω
Answer :
3.75 × 10–3 Ω
Solution :
Since G and S are in parallel
VG = VS
3 mA × 10 = 8 A × RS
RS = 3.75 m Ω
