I am using some wire-wound resistors (large white blocks) just so i can experiment with some LEDS. There rated at 5w, and by my maths the circuit is putting 3.1w out these resistors. I realise there may get warm, but there so hot i couldn't touch them!
Is that normal on wire-wound resistors well within there ratings ?
