XL 2πfl
Inductor device manufactured have specific inductance.
Inductive Proximity Switch type sensing switch that uses electromagnetic coil
to detect the presence metal object without coming into
physical contact with it.The symbol for
impedance “Z. Inductive reactance directly proportional to
frequency (f) and inductance (l).
” The unit for impedance the ohm.
Air Core Inductor
Iron Core Inductor
. Inductance designated the symbol “L
” and is
measured henries.17
Impedance The total opposition alternating current.The symbol for inductive
reactance “XL
”The unit for inductive reactance the ohm. Impedance is
the vector sum resistance and reactance.14
Inductance The property electrical circuit that opposes changes in
current.
