from the diagram above the inductive reactance ... - JAMB Physics 2007 Question
A
50Ω and 45Ω
B
25Ω and 51Ω
C
20Ω and 50Ω
D
10Ω and 50Ω
Ask EduPadi AI...
Correct Option: D
The inductive reactance is given as
Xl = 2πfl
= 2 x 50/π x 0.1
= 10Ω
Again from ohms law,
R = V/I = 75/1.5 = 50Ω
∴ Thus the inductive reactance and the resistance are respectively 10Ω, and 50Ω
