. Inductive reactance directly proportional to
frequency (f) and inductance (l). An
inductor often made from coil wire and sometimes
called coil choke.The symbol for
impedance “Z.
” The unit for impedance the ohm.The symbol for inductive
reactance “XL
”The unit for inductive reactance the ohm.14
Inductance The property electrical circuit that opposes changes in
current.

Inductive Reactance The opposition alternating current resulting from circuit
inductance.
Inductive Proximity Switch type sensing switch that uses electromagnetic coil
to detect the presence metal object without coming into
physical contact with it. Inductance designated the symbol “L
” and is
measured henries.17
Impedance The total opposition alternating current.
