good show Leigh!
one of MY random questions on impedance, mulled over for some the years.
Electrical resistance of course is V / i ( or Z = E / j for the
sophisticates )
Power is (V) x (i.).
My question (suspicion) is:
are other impedances also going to be expressed as the ratio of an
intensive variable to an extensive variable - with the product of
these two variables being power???
a 'simple' system to analyze would be a spring loaded gun shooting a
projectile of mass m.
and what IS the impedance of a simple lever system?
