COMEDK · Physics · 19. Current Electricity
A certain current on passing through a galvanometer produces a deflection of 100 divisions. When a shunt of one ohm is connected, then the deflection reduces to 1 division. The galvanometer resistance is
- A \(100 \Omega\)
- B \(99 \Omega\)
- C \(10 \Omega\)
- D \(9.9 \Omega\)
Answer & Solution
Correct Answer
(B) \(99 \Omega\)
