i am connecting a led with 100k 1 watt series resistor in 230v ac line the led is glowing. my doubt is whether led will fail in ac voltage are it will work fine? led used is normal red to red 5mm led .
We sometimes design with a xtor C-E reversed to get a low gain follower and some commentators have opined that it is not reliable.
note avalanche current flow in zeners and leds and BE junctions and normal diodes, fets... - all non destructive.
