Hi, I have a significant voltage drop across a power supply to the load, and I want to measure the resistance of the connections. There is about 6 ft of wiring from the power supply to the load, and with some connections/junctions along the way.
I calculated roughly 0.3 ohm of resistance (based on supply voltage of 1V, voltage and current at load (0.7V and 1A)) which I believe is way too high. The copper wiring has a cross section of 0.75mm^2.
I want to measure the resistance using this multimeter:
I wonder if the fact that the leads on the multi-meter being so long would give me inaccurate measurements? Would the resistance of the leads be added to the actual resistance of whatever you are measuring?
