T-21 diode module for G08 and G11 series universal relays, by Mors Smitt
Electronics - Mains 230V AC is rectified by D1, which reduces it to a safer level through 33-kilo-ohm resistor R1. Capacitor C1 (470µF, 100V) charges through diode D1 and resistor R1, which

should i consider peak value or vrms value for finding the value of resisstor? given vrms is 230v and diode specs are 3.6 v and 20ma? talked to a person who knows
