• Measure the power consumption of an output device

Power consumption of an output device

We measured the power consumption of a WS2812B RGB LED strip. We measured the power consumption of 7 solid colors and one fire animation where the leds were flickering.

Using Ohm's law we calculated the power consumption in Watts using this formula: P = V x I

Example: P = 4.9V, V = 0.06A, We can find I (WATTS) with I = P X V

I = 4.9V X 0.06A = 0.294W
