I need to generate a 500 volt electrostatic charge. How can I do this? I don't have a Van de Graaff generator. What are some practical suggestions? Basically I want to do experiment in which I need to induce charges on a plate ie one side positive and another side negative, so what are some practical suggestions for me. One of the approach is to place a metal plate inside a high voltage capacitor, how practical is this approach?

2umm please be careful, especially if fooling around with HV caps. And ask the EE stack if you can. This one is more mechanical and "other" engineering. – Pete W Dec 07 '21 at 03:41

1There are [*voltage multiplier*](https://electronics.stackexchange.com/search?q=voltage+multiplier) circuits which utilise **diodes, capacitors and a periodic low voltage waveform** to create large voltages. – AJN Dec 07 '21 at 12:50
