Power-Induced Thermal EMF Error Voltage (Product Demo) - VFR

In addition to uneven heating from outside sources, resistors are subject to differentially distributed internal heating from their own power dissipation. This internal heat generation operates upon the resistor's element-to-termination junctions to induce a net error voltage across the junctions of diverse materials. The error voltage is equivalent to a battery inserted into the circuit. For the low resistance values typical of current sense resistors where power dissipation is relatively high, the error voltage can be significant. This video is a real-time demonstration of that error and compares the performance of two resistor technologies. Less
