A 2H inductor has negligible resistance and is connected to a 50/π Hz A.C. Supply….

A 2H inductor has negligible resistance and is connected to a 50/π Hz A.C. Supply. The reactance of the inductor is
  • A.
    200 Ω
  • B.
    50 Ω
  • C.
    100/π Ω
  • D.
    25/π Ω
Correct Answer: Option A
Explanation

Inductive reactance is given by
XL = WL = 2πfL
XL = 2 x π x (50/π) x 2
XL = 200Ω
