Measured in ohms
WebMar 26, 2016 · Ohm's law expresses this relationship as a simple mathematical formula: In this formula, V stands for voltage (in volts), I stands for current (in amperes), and R stands for resistance (in ohms). Here's an example of how to calculate voltage in a circuit with a lamp powered by the two AA cells. Webaffect the sign of the voltage measured. We need to affirm that the meter is always placed in the anticipated orientation with respect to the “positive” and “negative” probes. On our MN35, the positive probe is generally the red-colored cable plugged into the V-Ohm-mA jack and the negative probe is
