The resistance of shunt is:
Correct answer: B. Very small
- A. Very large
- B. Very small
- C. Both (a) and (b)
- D. None of these
Explanation
The resistance of a shunt resistor used in an ammeter is very small. Typically, the shunt resistor has a much lower resistance compared to the internal resistance of the galvanometer. This ensures that most of the current flows through the shunt resistor, effectively bypassing the galvanometer coil. By using a shunt resistor with a very small resistance, the ammeter can accurately measure high currents without significantly affecting the circuit being measured.

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.
