The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Faraday as a Discoverer by John Tyndall: Let us push the analogy a little further; suppose in the case of the
fluid rendered viscous, as assumed a moment ago, the viscosity not
to be so great as to prevent the formation of ripples when the hand
is passed through the liquid. Then the motion of the hand, before
its final conversion into heat, would exist for a time as
wave-motion, which, on subsiding, would generate its due equivalent
of heat. This intermediate stage, in the case of our moving wire,
is represented by the period during which the electric current is
flowing through it; but that current, like the ripples of our
liquid, soon subsides, being, like them, converted into heat.
Do these words shadow forth anything like the reality? Such
