AC1 Fundamentals Unit 4 – Inductive Reactance


Impedance (Z) is a phasor. Resistance (RT) and inductive reactance (XLT) are the components


of the impedance phasor.


Being a phasor, impedance also has a phase angle.


The angle between the generator voltage and current is the phase angle of the circuit. The
impedance angle is equal to this phase angle.


NEW TERMS AND WORDS


inductive reactance (XL) - the opposition to the flow of alternating current by the inductance of
a circuit. It is measured in ohms.
phasor - a quantity consisting of magnitude and direction used to describe an ac waveform.
