WebAmateur radio operators (hams) or anyone who builds or experiments with radio transmitters should have and use a good dummy load. I noticed 100 watt 50 ohm resistors on eBay listed at five for $6.50 or one for $1.99. As the resistors were designed to be used as RF loads, I decided to make a good dummy load using only tools that most homes have. WebMar 24, 2014 · Re: 20-500amp programmable, 12volt, dummy load? « Reply #7 on: March 21, 2014, 11:34:02 pm ». For 0.024 ohm you could just use some thick and long wire, and cool it in a bath tube. Even @2000W it would need some time to increase the water temperature. But the contact resistance to the battery might be a problem.
