Why Voltage Alone Can Mislead You | PowerFlow™ Explained

A circuit can show voltage and still fail when it actually has to do work. In this deep dive, John from Power Probe explains how unwanted resistance from corrosion, dirty connectors, damaged wiring, or poor connections can create voltage drop and reduce the performance of an electrical component. Using a simple lighting circuit as an example, John breaks down how available voltage is shared across resistance in the circuit—and why checking voltage alone may not reveal the complete problem. That’s where PowerFlow™ comes in. By applying a controlled load to either the positive or negative side of the circuit, PowerFlow™ allows technicians to expose voltage drop under load and identify hidden resistance that might otherwise go unnoticed. See why proper circuit loading can make the difference between guessing at a fault and confirming exactly what is happening in the circuit.
