well
See the link between frequency and current (all else being equal)
Where the “bell curve” comes from
Look at how to minimize impedance and (therefore) maximise current
How to “balance the load”
Extend the above to industrial Power Factor Correction
How to make the phase angle as small as possible
See the reprise of resonance How bridges and “The Edge” are linked
Set some HRT, check our website schedule and revisit our time plan between now and 25 November
How to make the best possible use of time.
