All parts of this circuit should be regarded as being at mains voltage at all times. It can kill anyone who touches it.
Note that in the comments someone says
- Capacitor in parallel to R1= 0.47 Microfarad 450V
Note that it should be a 450V cap for 230 VAC mains.
And it should be an X rated cap (across mains use).
The capacitance will affect the current provided.
Current will VERY APPROXIMATELY be V x 2 x Pi x C
At 110VAC, 60 Hz
Ima ~~~= 40 x CuF
So for 1 uF I ~= 40 mA.
I have ignored R2 as impedance of the capacitor dominates.
Diode polarity matters.
