Which one of the following devices does not function like an electric motor
Correct answer: C. Voltmeter
- A. Galvanometer
- B. Ammeter
- C. Voltmeter
- D. Transformer
Explanation
An electric motor converts electrical energy into mechanical energy, and devices like galvanometer and ammeter are not typically designed to function as motors.A voltmeter measures the potential difference (voltage) between two points in an electrical circuit. Unlike a galvanometer or ammeter, a voltmeter is not designed to function as an electric motor.Therefore, the correct option is (c)

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.
