Measuring resistance of resistor
WebDec 20, 2009 · To measure the resistance of a resistor, one must have a multimeter handy. The following steps should be followed in order to correctly measure the resistance: Switch the dial to the 200 Ω range, if it is not already there. The black lead must be connected to the COM terminal. The red lead is connected the terminal labeled Ω. WebStep 1: Measure the Resistance of an Individual Resistor A. Create the circuit Place the two resistors on the breadboard so that none of their terminals are connected to one another. Once on the breadboard, place the mode selector on your DMM to the Ω symbol. Ensure that your leads are plugged into the V-Ω and COM ports.
