Is unaffected by the supply frequency
Decreases with the increase in supply frequency
Increases with the increase in supply frequency
Becomes zero with the increase in supply frequency
Answer is Right!
Answer is Wrong!
The correct answer is: B. Decreases with the increase in supply frequency.
Inductance is a measure of how much an inductor resists changes in current. The inductance of a coil is proportional to the number of turns in the coil and the permeability of the core material. The inductance of a coil is also inversely proportional to the square of the supply frequency. This means that as the supply frequency increases, the inductance of the coil decreases.
Here is a brief explanation of each option:
- Option A: Inductance is unaffected by the supply frequency. This is not true. The inductance of a coil is inversely proportional to the square of the supply frequency.
- Option B: Inductance decreases with the increase in supply frequency. This is true. The inductance of a coil is inversely proportional to the square of the supply frequency.
- Option C: Inductance increases with the increase in supply frequency. This is not true. The inductance of a coil is inversely proportional to the square of the supply frequency.
- Option D: Inductance becomes zero with the increase in supply frequency. This is not true. The inductance of a coil can never be zero.
