When a galvanometer used as an ohmmeter gives full (maximum) deflection, it indicates
Correct answer: B. infinite resistance
- A. zero resistance
- B. infinite resistance
- C. small resistance
- D. intermediate resistance
Explanation
B is the correct answer. When a galvanometer used as an ohmmeter gives full deflection, it indicates that the resistance in the circuit is infinite. This means there is no current passing through the galvanometer, suggesting an open circuit.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
