Ammeter is a galvanometer with:
Correct answer: D. Low resistance in parallel
- A. High resistance in series
- B. Low resistance in series
- C. High resistance in parallel
- D. Low resistance in parallel
Explanation
An ammeter is a device used to measure the current flowing through a circuit. It is connected in series with the circuit. To measure the current accurately, the ammeter should have a very low resistance so that it does not alter the current flowing in the circuit. If the ammeter has a high resistance, it will cause a significant voltage drop across it, reducing the current flowing through the circuit and giving an inaccurate reading.

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.
