For accurate measurement of current through a circuit, the resistance of ammeter should be:
Correct answer: A. Very small
- A. Very small
- B. Very high
- C. Neither small nor high
- D. None of the above
Explanation
For accurate measurement of current through a circuit, the resistance of the ammeter should ideally be very small. This is because the ammeter is connected in series with the circuit, and any resistance introduced by the ammeter itself would affect the total resistance in the circuit, thereby altering the current flowing through it. By having a very small resistance, the ammeter minimizes its impact on the circuit and ensures that the measured current closely reflects the actual current flowing through the circuit components.

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.
