The effect of light emission intensity by varying the voltage, current and distance / Mohd Azuandi Adzami

When current passes through a light-emitting diode (LED), the LED emits an incoherent narrow spectrum of light. The relationship between the voltage, current, distance and the light intensity of an LED is studied in this research. Voltage ranging from 3.68 to 16.44 Volts was applied to a blue, red a...
