calculate resistor values?
Need help from you electrical geniuses. I bought a new interior switch for my LED light bar that matches the OEM headlight switch. The specifications of the switch are below. Note the bottom where a formula is given to calculate the resistor needed.
I did this but have no idea what to do with the number? Which by my math is 1.
Supply Voltage is 12V
LED Forward voltage = 2V
LED Forward current = 10ma
Resistor value = 12-2 / 10 = 1
Please help me, Feeling really stupid right now.
