An alternating voltage source V = 260 sin ( 628 t ) is connected across a pure inductor of 5 mH . Inductive reactance in the circuit is:
Options
- A3 . 14 Ω
- B6 . 28 Ω
- C0 . 5 Ω
- D0 . 318 Ω
Correct answer
A. 3 . 14 Ω
Step-by-step solution
Comparing the given equation of AC voltage with standard expression, V = V 0 sin ω t , we get ω = 628   rad   s - 1 . Inductive reactance is given by, X L = ω L . = 628 × 5 × 10 - 3 = 3 . 14   Ω
