plz check the attached circuit for Moc3022 and triac is this OK, the reason for asking is that the values of resistors 180 and 2.4k i have seen them in 115 V ac circuits... and the calculations lead us to this values, but even in some data sheets with 220v the same values are used in typical application circuits..
what should be the values for 220V ac
