Use LoggerPro to show the rise and
fall of the current and the inductor voltage.
The time constant is large enough that the demonstration ammeter
(202-19-E) could be used to show the rise and fall of the
current, instead. Use the 25 mA shunt.
NOTES
The inductor has an internal
resistance of about
130 ohms.
The labeled inductance is 900 H; its
measured inductance in this situation is 450 H, but varies with
current.
Io = V/R = 26 mA
τ = L/R = 2.0 s.
