To convert a galvanometer into an ammeter, we connect with it a:
Correct answer: C. Low value by pass resistor
- A. Shunt resistance
- B. Low value parallel
- C. Low value by pass resistor
- D. All of above
Explanation
A bypass resistor, similar to a shunt resistor, provides an alternative path (bypass) for the main current to flow, effectively diverting most of the current away from the galvanometer coil. The low-value of the resistor ensures that only a small fraction of the current passes through the galvanometer coil, allowing it to measure the current indirectly. This configuration converts the galvanometer into an ammeter suitable for measuring larger currents.

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.
