A shunted galvanometer is called:
Correct answer: B. Ammeter
- A. Voltmeter
- B. Ammeter
- C. Ohmmeter
- D. Potentiometer
Explanation
A shunted galvanometer is typically referred to as an ammeter. An ammeter is an instrument used to measure electric current in a circuit. It is connected in parallel with the circuit (shunted) so that it has a very low resistance to minimize the impact on the circuit's operation. This low resistance allows it to measure the current flowing through the circuit without significantly affecting that current. By shunting a galvanometer with a low-resistance shunt, it can be effectively converted into an ammeter to measure higher currents while maintaining good accuracy.

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.
