Hi All !
I am ashamed to ask, but just to check if I am correct with this.
I wanted to connect a series of LEDs direct to the mains. (230V/50Hz)
Therefore I need 10... 15 kOhm in series.
I calculated 1 / ( 2 x pi x 50 x 220 nF ) and came to 14.468 Ohm.
Is this correct for this situation ?
I will use an extra 1 or 2,2 kOhm resistor in series, and for safety
a zener parallel over the LEDs. Perhaps the 1 or 2,2 kOhm resistor
`below` the zener.
Kind regards,
Edwin
