actually, the voltage rise due to ohmic loss is a tiny fraction of
the
rise due to L*di/dt. Typically, a lightning stroke might have a
di/dt
of 10kV/us for a smallish stroke. With 1 microhenry inductance
(about a
meter of any conductor, strap, wire, any size) that's 10kV.
In the interest of physical accuracy, di/dt can't have the units of kV/us.
What was
meant is obviously kA/us.
73,
Yup.. Not some special volts^2/second unit..
