So the car battery produces 12 volts. Let's say I want to light up a single
LED with the car battery. Is this possible?
V=12V
I=20mA
R=?
V=IR
R=V/I=12/0.020=600ohms
So if I hook up a circuit in parallel with the rest of the circuitry that
goes off the battery, and I place a resistor of 600OHMs and a single LED,
will it light up? Does the size of the wire I use matter?
TIA!
