Basically, I have a circuit, square wave inverter, I have 4 1/2w 270R resistors , which are getting too hot too touch. But i can leave the circuit on for hours and the resistors havnt burned out. I am wondering if im missing something, and if so do i need some higher wattage resistors . Iv tested with one bulb and they get as hot as all three bulbs.
