The inductive reactance, XL=2 π v L=2 × 3.14 ×(50 s -1) ×(30.0 × 10-3 H ) =9.42 Ω

Q. In a purely inductive $A C$ circuit, $L = 30.0 m H$ and the rms voltage is $150 V$ , frequency $v = 50 Hz$ . The inductive reactance is

$15.9 Ω$

$9.42 Ω$

$10 Ω$

$8.85 Ω$

The inductive reactance,
$X_{L} = 2 π vL = 2 \times 3.14 \times (50 s^{- 1}) \times (30.0 \times 1 0^{- 3} H)$
$= 9.42 Ω$

Q. In a purely inductive AC circuit, L=30.0mH and the rms voltage is 150V, frequency v=50Hz. The inductive reactance is

15.9Ω

9.42Ω

10Ω

8.85Ω
