MCQ
If the current is doubled, the deflection is also doubled in:
- AA tangent galvanometer
- ✓A moving$-$coil galvanometer
- CBoth
- DNone of these
✓
Answer
Correct option: B.
A moving$-$coil galvanometer
In $\text{MCG,}$ deflection is proportional to torque on the coil and torque is proportional to current.
Hence, when current is doubled, deflection is doubled.
