Question

find the reactance of coil of inductance 100mh at a frequency of 50hz​

Answer 1

Answer:

==========================

Here, L = 10 mH = 10 * 10 ^-3 H = 10 ^-2

Hfrequency = 100 Hzusing, Xl = Lω = L *

2*π*frequency∴ Xl = 10^-2 * 2 * 3.14 *

100 = 6.28 ohm==========================

Answer 2

Given:

Inductance = 100mh

Frequency = 50hz

To Find:

The reactance of coil of inductance

Explanation:

Let F₁ be 50hz

L = 100mh = 100 × 10⁻³ H

  = 10⁻¹H

X(L) = LW

  = 2πFL

  = 2×3.14×50×10⁻¹

  = 31.4Ω

Answer = 31.4Ω
