Capacitive supply...

Good day.
What is the voltage at C2 for this supply method ? If not allowed in the forum, please delete.

Hello,

@Externet , Your circuit shows a voltage doubler.

We strongly discourage the use of this kind of "power supply". It is extremely dangerous since the "low voltage" side is still directly connected to mains. This is highly unsafe!
