If the frequency of the e.m.f. source in the a.c. circuit illustrated above is (frac{500}{pi})Hz. What is the reactance of the inductor?
  • A.
    450
  • B.
    0.9
  • C.
    900
  • D.
    567
  • E.
    43
Correct Answer: Option C
Explanation

x = 2(pi f L = 2pi times frac{500}{pi} times 0.9)
= 900(Omega)
