With a 220v bulb example how low z would need go to burn it

Let's say it burn with 250v 2kw of power that is 8amps

So if we are applying the correct frequency for the impedance transformation it would require a impedance of 27 ,5 ohms

So even applying 220v it will consume 8 amps and burn the lamp

This is just an example of how the transmission line can transform the impedance

The interesting about impedance calculator is that if the diameter is equal to the distance the impedance is zero...

I believe is because it become like a short So to increase impedance we need small separation

The separation between the wires tells the impedance they will have...

My best guess as I said to reduce the length we could increase the capacitance of the line and capacitance accordingly... this would have the effect to reduce the length required for the frequency used

How to increase cell impedance? Ferrite

Pot core

The cell in this case is like the continuation of the wire...

To get the results of what is happening I believe the only way is getting the readings of current input vs output of the coils with analog isolated meters... it will affect impedance but anyway is the only possible manner to read current transformation specialy if load is not a resistor

The voltages also can be compared on input and output using an isolated probe on the end side for example

If we manage to make a transmission line with 3ohms or so with enough meters to resonate at low frequency than we gona see some nice action...

Otherwise I could be wrong in this analysis and the cells were referential to one or two isolated grounds inside the water bath maybe outside the cell making is impedance higher perhaps

But anyways the lower is the impedance of the tl the higher will be the power it can deliver to a load...

The power is not limited to the input impedance vs the input voltage in this little thing because of the reflections

And that's why I'm saying if the impedance of the load is too low vs the impedance of the line the line will not be able to do much with the load since the power is limited

The current input will be reduced by the reflections

You see?

To get the power to real kick in the impedance must lower than the load

Anyway those are only thoughts and words...

https://www.mantaro.com/resources/impedance-calculator.htmThis is a calculator you can take a look

To find the z of the chokes we just need some experiments with different values of resistors

And reverse engineering it measuring the input current vs output current and hitting with 1/4 wave length

Ah dip the coil in a liquid will decrease the impedance

And if is pure water it reduces more!
