How voltage amplification affects plasma flux density?

Click For Summary
SUMMARY

Voltage amplification significantly impacts plasma flux density and magnetic field strength, even when power output remains constant. In the example of a USB plasma globe operating at 300mA and 5V (1.5W), amplifying the voltage to 1000V results in a current of 1.5mA, while further amplification to 10,000V reduces the current to 1.5µA. This demonstrates that increasing voltage while maintaining constant power leads to a decrease in plasma density due to the inverse relationship between voltage and current for a fixed power output.

Would a voltage amplification with the same power output increase plasma density and increase the magnetic field of the plasma, if the power output does not change?

In the case of a USB plasma globe with a current flow of 300mA through 5 volt, amounts to 1,5W.
CASE A:

Ofcourse this voltage has to be amplified in a transformer to at least 1000 volt, in that case the current would be nominal 1,5mA.

CASE B:
Now what if we amplified the voltage up to 10'000 volt, the current would be 1,5 micro ampere.
How would this affect the plasma?
--------------------------------------…
Question 2:
What is the ideal voltage to current ratio for any given power?

The plasma density for a fixed gap will generally depend on the current, so increasing the volatge and keeping the power constant will produce a lower plasma density.
