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