NettetIt’s easy to identify LED terminals. The long and positive terminal is the anode, while the short and negative terminal is the cathode. Then, set your multimeter knob on diode mode. Connect your probes so that your LED enters a forward-biased condition. Your LED will glow if it’s healthy or remains dark if it’s faulty. NettetLED Working. Like an ordinary diode, the LED operates only in forward bias condition. When the LED is forward biased, the free electrons cross the PN junction and recombine with holes. Since these electrons fall from a higher to a lower energy level, they radiate energy in the form of photons (light).
