Inductors - Technical MCQs

Q1:

What is the inductive reactance if the Q of a coil is 60, and the winding resistance is 5 omega.gif?

A 0.083 omega.gif

B 12 omega.gif

C 30 omega.gif

D 300 omega.gif

ANS:D - 300 omega.gif

Q = Xl/R.
Xl = 60*5=300;
Xl = inductive reactance.
Q = quality factor.
Note: T= L/R.
