Question

etermine the solenoid impedance. *
49. A solenoid coil with a resistance of 30 ohms and an inductance of 200 milli-henrys, is connected to a 230VAC, 50Hz supply. Determine the solenoid impedance.

Answer 1

Answer:

69.59 ohms

Explanation:

Given that

L=200\ mH

F=50\ hZ

R=30\ ohms

For inductance

$X_L=2\times \pi\times f \times LX_L\\=2\times \pi \times 50\times 200\times 10^{-3}\\=62.8\ ohm$

$R=30\ ohmsImpedance\\Z=\sqrt{R^2+X_L^2}\\Z=\sqrt{30^2+62.8^2}\ ohms\\Z =69.59\ ohms$
