Malcolm -
That is correct for the normal AC circuit. However, the TC is a dual RCL
system and changing the coil self capacitance (distributed) of the secondary
circuit will change the impedance of the circuit. The impedance change also
changes the effective resistance losses when the frequency is changed.
