The question is:
If the supply voltage is 100v ac with a period of 20ms, and the supply current (Is) taken by the coil is 6A, calculate the frequency of the supply, overall impedance, Inductive reactance and the inductance of the coil.
I've worked out the frequency to be 50Hz and in order to get the Inductive reactance I need to work out the inductance of the coil.
f = 1/t
1/20ms
1/20x10^-3 = 50hz
Z = v/I
Z= 100/6
Z =17.6
Xl = sqroot z^2 - r^2
17.66^2 - 100 = 13.24
2pifl
L =xl ÷ 2pif
13.24 ÷ 2 x pi x 50=
0.04H
Just want to double check any help??
