Where does it say 30,000 V? It says that it depends on the dielectric strenght of the medium (For air: 30kV/m), which naturally depends on the distance also, for a constant voltage. I have a 9V battery in my hand with a wire from each terminal. When I touch the two together I can see very small sparks.
"High voltage" is considered 35,000 volts or more. This does
not mean that 35,000 volts or more is required to create a spark.
You can also break down a diode/insulator, with high frequency. Just like disconnecting a battery causes that 30,000 volt spark. When you alternate or pulse at very high frequencies. You can create heat, you can create, a near vacuum. And you can create ARC.
No when you can run whatever frequency signal you want through a capacitor, and the only thing that will change is the capacitive reactance.
You can run whatever frequency you want through a diode, the only thing that happens is a rectification.
Neither component will fail unless you exceed the maximum rated voltage or current....which is irrellevant to frequency.
A spark is a potential of 30,000 volts. I will bet my life on it. High frequency can make that happen, with lower voltage.
Get the nearest 9V battery, turn off the light and touch together the terminal wires. Then video it and upload it, if you want.
