What is an Inductor?
(continued)
The American inventor
JOSEPH
HENRY discovered the above relationship.
-
His name is associated with the
unit of inductance.
-
Experimentally, one henry is the amount
of inductance (L) that permits one volt
to be induced (V) when the current through
the coil changes at a rate of one ampere
per second.
-
In most applications the henry is
a large unit and it is common to see
component values in microhenries (µH)
and millihenries (mH).
A coil of wire is shown in Figure
