I want to power a LED with 120 VAC. I set up a circuit like the one in the attached file. I sized the resistor with ohm's law. I wanted 20 ma so that means a 6.8 K resistor with a minimum of 2.4 watts. So I used a 3 watt metal film resistor. even so it gets very hot. Is this normal?????????????? Where am I going wrong??????????? do people use a driver at that voltage????????? it would look goofy to use a 5 watt. please help.
