AC Circuit

Question

Answer 1

The impedance is combination of resistor and inductor connected in series.

The impedance in polar form, Where is the phase angle and is the phase angle.

Find the magniutde of the of the impedance.

Find the phase angle of the of the impedance.

Phase angle can be found by power factor.

Find the power factor.

Therefore, impedance .

For inductor, the impedance is .

in complex form can be written as

For capacitor, the impedance is .

in complex form can be written as

Power factor is
