Determine the inductive reactance when a 30 0mH... - JAMB Physics 1993 Question
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 option: c
XL = 2\(\pi\)FL
= 2 x 3.142 x 30 x 10-3 x 1.3 x 103
= 245\(\Omega\)
= 2 x 3.142 x 30 x 10-3 x 1.3 x 103
= 245\(\Omega\)
