The impedance of the perfect voltage source is supposed
to be zero. I, like you, suspect that is a complete
impossibility. What I would like to see is a TV signal
fed through a source only to emerge unscathed on the
other side and viewable on a TV screen without distortion
just as the theory predicts.
My thinking keeps evolving, so new twist emerge.
If the impedance of the perfect source is zero, what limits the power
output from the source? If the limit is supplied by the load, then the
perfect source has evolved into a real source as soon as the circuit has
been defined.
