Hello. Let's say you have a antenna leading into a parrell lc circuit and from the lc circuit the current leads to a non transistor with a base turn on amps at three amps for current to flow from collector to emitter or a lc circuit in series with a non transistor after the lc circuit with a base turn voltage of 3 volts.

Will the tank circuit resonate amps ( parrelle) or resonate volts (series) until it reaches the volts or amps to turn on the transistor even if it's millivolts or milliamps input from the antenna.

And if this is so once the base voltage or amps are meet to turn the transistor on will it draw three volts or amps from the tank circuit leaving less than three volts or amps in the tank circuit or will the resonance keep a constant three volts or amps flowing through the transistor. Thanks.

Neither, it will remain at millivolts and microamps forever.

Though I cannot say for sure since I don’t know what a non transistor is.

The tank circuit will dissapate all the energy from the antenna as it comes in, it will not build up like you seem to think.

Doesn't a parrell tank circuit resonat amps and thus build up amps and wouldn't a transistor with switch on at it's base at three amps cause the tank circuit to resonant up to three amps before current from the tank circuit can flow from collector to emitter.

 

A resonant circuit takes the energy you put into it and transfers
its energy in a cyclic manner back and forth between the L and
the C in the tank. But does not manufacture energy. In fact the
tank circuit, its L & C, have losses, they are not ideal. and so you
have to keep supplying those losses or the circuit will decay to 0
energy state, where all its energy is converted to heat in those losses.

This is something akin to what you would see if you pulsed some energy
into a tank circuit and then stopped supplying it energy. It decays over time.

Also, transistors do not just "turn on" at a specific current. There are circuits that can be made to snap on at a specific voltage (or current with the addition of a resistor) but they involve more than one transistor. And any such circuit will extract some energy from whatever is driving it.

And 3 Amps would be a ridiculous current to turn on a transistor. This would be needed only in a circuit that was handling something like 30A, and the 3A to turn it on is basically wasted, dissipating about 2 Watts or more of power.
