Electronic – How possible is producing very high voltage and electric arc by a using this simple setup

arclcrpassive-networks

I have the basic series RLC circuit in simulation below.
As one can see in SPICE simulation, the output voltage at resonance frequency goes upto 1KV:

enter image description here

Can I really obtain that much voltage as in the simulation in practice by using a function generator and setting the input to around 1.6MHz(resonance freq.)?

Does it also produce a visible continuous electric arc if a grounded metal plate is placed in the vicinity? Or would the function generator's current will be an issue?

Or the resonance will displeasure if there will be some discharge?

I wonder what kind of practical challenges or issues I might encounter.

Edit:

2nd version with the ideas from glen_geek to make it as realistic as possible:
..
I increased the inductance to 10mH. Something like this: https://images-na.ssl-images-amazon.com/images/I/414-dRJ5jTL.SX425.jpg
Now I took account parasitic capacitances, output impedance of function generator ect. And increased the input voltage amplitude from 1V to only 2V.
Here I still can get 1kV at 290kHz:

Is it really possible in real? If so how many mm plate gap I need to obtain a continuous electrical arc at 1KV?

Best Answer

Your simulation is incomplete for practical components. A function generator is mentioned as a signal source (of unknown type)...these generally have an internal source resistance close to 50 ohms, not 1 ohm. This will limit the power available - however function generators often can supply 20 V peak-to-peak with no load. A square wave source will provide slightly more power than a sine wave.

A practical inductor will have both internal resistance, and capacitance. In addition, any wire or plate you attach to its "hot" end will add capacitance. Nevertheless, your approach to generating higher AC voltage is OK: it is possible to boost amplitude to hundreds of volts from a standard type function generator.

schematic

simulate this circuit – Schematic created using CircuitLab The values of the inductor's parasitic components are guesses, and depend very much on the actual inductor you have available. A wire attached will also radiate a little energy away, reducing voltage.
Since impedance is high, any sparks will be feeble. A function generator should be protected by its 50 ohm internal resistance if it is of sound design.
