Hi I need to build a circuit to wast 35 amps at 3.3-12volts. The reason is I am going to do load testing on a PCU and try to fry some cheap connectors. I want to do it free or super cheap ($5 or under). I have lots and lots of spare parts. open to all wastful circuit ideas.

Edit 3.3-12 volts DC

 

First you need a 500Va or over variable supply.
So the $5 cap may be a limiting factor.
Max.

Just take it for what it's worth: an idea
The low voltage light bulb idea might lead to the idea of using the space heater you left in a closet 20 years ago or some 500 watt work lights you have in the garage.

Will a ac space heater work?

Certainly.

 

While we're on heaters, the heating elements out of a kitchen stove and/or the oven heater.
The heating elements out of a water heater.

(You will need more heaters rated at 120 volts or 240 volts than you would need if you could find 12V heaters.)

Thanks for the ideas I think I have a heating element from a kitchen stove.
