@professorbutlerfb: Most techs think their meter is measuring voltage… but it’s really measuring the difference in potential between two points. Same idea as HVAC: you’re not ‘making cold,’ you’re moving heat. Once you reprogram your brain to see electrical potential the same way, troubleshooting becomes a completely different game. This video breaks down how your multimeter actually thinks, why the black probe matters, and how potential difference exposes what’s really happening in a circuit. #HVAC #HVACTech #ElectricalTroubleshooting #MultimeterBasics #PotentialDifference
