Default Antenna Theory Question

- an ideal electrical engine (no ohmic loss, no friction) fully
transforming the applied electrical power into mechanical power. It looks
like a resistor, but no heat is generated anywhere


No, it looks like a resistance, not a resistor. There is one
IEEE definition for resistor. There are two IEEE definitions
for resistance. A resistor with current dissipates power. A
resistance may or may not dissipate power. One definition of
resistance in the IEEE describes a dissipationless resistance.
There is no such thing as a dissipationless resistor.


It IS a resistance, but it LOOKS like a resistor because, from the exterior, one
has no means to determine whether energy gets dissipated or transformed in some
other form.
