I have a Roll of LED Lights.
And it is Rated 12 Volts at 4. Watts Per Foot.
So I Cut 1. Foot Off of the Roll.
So this will work on 12 Volts at 4. Watts.
But if I want to Find Out the Current it needs I will use the PIE Formula.
P Divided By E = Amps.
So I will do 4. Divided By 12 = 0.333333333 Amps.
So can I just take this to the Third Number like this 0.333?
And would this be 0.333 mA?
Or do I not Understand this?
