Simple Current limiter

You can adjust the resistors.

This is based on circuits I've seen and a combination of my Power Supply Current Limiter. This is the best I've been able to come up with.

As long there is no negative feedback its a perfect method to destroy any transistor. Doesn't matter how big. It would need an oversized heatsink to compensate that. Starts with 7W in case of short but will quickly heatup and the current will also increase which will sooner or later destroy the transistor. Do a test with a cheap 2n3055 and keep an eye on current, and watch how the current is climbing.

Dont know your requirements current transistors etc here a current source with negative feedback. The heat sink must take 7W or any power you configure http://everycircuit.com/circuit/6463998517313536

Oooh, I was trying to do that but I didn't know how to execute it. Thanks for the explanation and the schematic.😀
