Determine the inductive reactance when a 30.0mH inductor with a negligible resistance is connected to a 1.3 x 103Hz oscillator.
-
A.
39.0(Omega) -
B.
122.5(Omega) -
C.
245.0(Omega) -
D.
39000.0(Omega)
Correct Answer: Option C
Explanation
XL = 2(pi)FL
= 2 x 3.142 x 30 x 10-3 x 1.3 x 103
= 245(Omega)
