In a pure inductive circuit if the supply frequency is reduced to 1/2, the current will__________?
Correct answer: B. be doubled
- A. be reduced by half
- B. be doubled
- C. be four times as high
- D. be reduced to one fourth
Explanation
For a pure inductor, Xₗ = 2πfL and I = V/Xₗ, so current is inversely proportional to frequency. Halving the frequency halves the reactance and doubles the current.
