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
