Supply voltage is 230 Need voltage is 4V Need current is 0.1A Need power is 4v*0.1A = 0.4W Then capacitor drop voltage is 230-4 = 226V capacitor heating power is 226V / 0.1A = 22.6W But it doesn't get hot like 22.6W What happen to the 22.6W ??
mehemai video eke clearly kiyala tiynwa R1 , R2 , D wala functions. Resistor values range dala tiyenwa. hodata balanna. terune nattam mata kata karanna. ස්තූතියි❤
