from the diagram above, the inductive reactance and the resistance R are respectively

Physics JAMB 2007

from the diagram above, the inductive reactance and the resistance R are respectively

  • 50Ω and 45Ω
  • 25Ω and 51Ω
  • 20Ω and 50Ω
  • 10Ω and 50Ω checkmark

The correct answer is: D

Explanation

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
