What is an LED?_ An LED (Light Emitting Diode) is a type of semiconductor device that converts electrical energy into light. _How does it work?— When a voltage is applied to the LED, electrons recombine with holes, releasing energy in the form of photons, which we see as light. _Key Characteristics:_ ���_Color_: LEDs are available in a range of colors, including red, orange, yellow, green, blue, and white. ��_Brightness_: Measured in lumens (Im) or candelas ���_Voltage_: Typically operate betwee

This simulation demonstrates the working of RGB LEDs driven by three sinusoidal AC sources at 1 kHz frequency. Each source powers one LED—Red, Green, and Blue—through a current-limiting resistor of 100 Ω. The current waveforms for the LEDs are shown at the top, where the red, green, and blue signals vary sinusoidally and independently. As the currents flow through the LEDs, the RGB light components combine to produce varying colors depending on the instantaneous current in each LED. This illustr
