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
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Inductive reactance is given by
XL = WL = 2πfL
XL = 2 x π x (50/π) x 2
XL = 200Ω
