Application Examples
4. Measure the current ramp. The inductance
is effectively de
fi ned by the slope of the
current ramp shown here.
5. Calculate the inductance using the
following formula:
where:
L is the inductance in henries,
E is the voltage of the pulse generator,
dt is the change in time, and
di is the change in current.
