raschemmel:
330k on each leg of the line.
220V x 1.414= 312V
312v/0.001A=312000=>330kI would recomnend 1 Meg for each leg to be safe.
230V ac mains
half wave or full wave rectified.
trying to get zero crossing, so there is no capacitors in this circuit.
1.414 ?
general question ;
what is your rule of thumb about a single resistor in a high voltage application ? at what point to you address flashover ? before you start using either a resistor designed for the voltage or start to use resistors in series ?
A simple 1/4 watt carbon 1meg resistor has a voltage limit of about 150v.
