Thanks for all the help guys, I ended up going with a 50 ohm 10 watt resistor and even fashioned a homemade heatsink complete with thermal compound to keep it cool. It works wonderfully and now my relay doesn't take 20 extra seconds to power off. I have been to some forums with some unpleasant...

The situation is already rigged up like crazy. Basically I've created a sequencer to power up audio amplifiers one by one

Thanks so much for the help! Would you mind explaining, just so I understand, why the resistor can be 100 ohm and not 68 ohm (like the math says)?

Sorry, I was using the wrong terminology. It's a DC power supply and there's a filter cap inside that I would like to discharge faster when it's unplugged. Initially I tried a 68 ohm 1/2 watt resistor but it nearly caught on fire (oops). Someone suggested a 100 ohm 2 watt resistor instead. Would...

This will (maybe) be an easy question to answer. Here is my situation: I have a 12v 200mA capacity transformer (wall wart) that I am using to power up a relay which takes about 5mA and has an input voltage range of 5-24v. Basically I need to burn off the other 185mA or so of the transformer's...
