i have a very silly question but i prefer to ask befor doing sth wrong.
How much current (A) can resist a normal sheet resistance??
I am trying to build a currentsensor with arduino for my RC -car with an ACS770. I measured that the motor of my RC-Car gets max. 170 A.
Now im trying to build a circuit to get at least 50-100A to test my built, but i dont have any current generator.
Ive thougt if a get 5v of Arduino or 9v of a baterry and I use a 10 1 Ohm resistance parallel I will get 50 or 90 A....
How can i do that, I dont think the thin cables of a sheet resistor can handle so much current?? Arduino can handle only 500mA and a normal 9v battery also cant handle 90A.....
