Hello. I'm building a circuit that calls for a current sensing resistor. Let's say it calls for .25 ohm, could I just use four 1 ohm resistors wired in parallel?
The power supply i'm currently considering is a switching 1A 12vDC wall-wart. Assuming that means i use 1A as my value for "I" (please correct me if i'm wrong, i'm a newb), then I would use four 1Ω 1/4w resistors?
