WebMay 29, 2024 · When a resistor fails, it either goes open (no connection) or the resistance increases. When the resistance increases, it can burn the board, or burn itself up. How do you know if a resistor is positive or negative? Resistors don’t care which leg is connected to positive or negative.

Many failures result in generation of hot electrons. These are observable under an optical microscope, as they generate near-infrared photons detectable by a CCD camera.
