Non-inductive resistances are used in _.
Correct answer: D. All of these options are correct
- A. Ammeter
- B. Voltmeter
- C. Resistance boxes
- D. All of these options are correct
Explanation
Non-inductive resistances are used in all of these.Inductive resistances can cause errors in the measurements made by ammeters, voltmeters, and resistance boxes. This is because inductive resistances create a magnetic field that opposes the change in current. This can cause the pointer to deflect in the wrong direction, or it can cause the measurement to be inaccurate.Non-inductive resistances do not create a magnetic field, so they do not cause errors in the measurements made by these devices. This is why non-inductive resistances are typically used in them.Here are some of the advantages of using non-inductive resistances:- They provide accurate measurements.- They are less affected by external magnetic fields- They are more stable over time.

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.
