Question

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

Answer 1

Hey there!!!

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

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

frequency = 100 Hz

using, Xl = Lω = L * 2*π*frequency

∴ Xl = 10^-2 * 2 * 3.14 * 100

                      = 6.28 ohm

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

Hope it helps!!
