[TowerTalk] SteppIR 40/30 and loading

[Bill Aycock]

Joe- I agree, so long as you are covering DC current, but our subject is 
AC. In your statement about creating or destroying energy, the third 
condition of storing energy seems to be neglected.  The creation or 
destruction of a magnetic field seems to be a means of breaking the balance 
of current in vs current out, as a function of time.
