Non inductive resistances are used in decreasing______________?
Correct answer: B. Self inductance
- A. Mutual inductance
- B. Self inductance
- C. Magnetic fields
- D. Heating effect
Explanation
A non-inductive resistor is wound so that the magnetic fields of adjacent sections cancel, making its net inductance very small. It is therefore used to reduce self-inductance, not heating, because resistance still produces heat.
