When the ohmmeter measures the infinite resistance, its pointer lies at
Correct answer: B. Left end of the scale
- A. Centre of the scale
- B. Left end of the scale
- C. Right end of the scale
- D. None of these
Explanation
An ohmmeter is a device used to measure the resistance of a circuit. The scale of an ohmmeter is typically calibrated in ohms, with zero resistance at the right end of the scale and infinite resistance at the left end of the scale.When the ohmmeter measures an infinite resistance, it means that there is no current flowing through the circuit. This is because the resistance is so high that it effectively blocks the flow of current. In this case, the pointer of the ohmmeter will lie at the left end of the scale, which corresponds to infinite resistance.

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.
