Explain the working principle of ldr
WebA SIMPLE explanation of a Light Dependent Resistor (LDR). Understand the working principle of a Light Dependent Resistor circuit, and exactly how an LDR sens... WebLEDs work on the principle of Electroluminescence. On passing a current through the diode, minority charge carriers and majority charge carriers recombine at the junction. On recombination, energy is released in the form of photons. As the forward voltage increases, the intensity of the light increases and reaches a maximum.
