So why not just use an appropriate resistor?
- nitrogen 13y agoThe voltage drop of a resistor is proportional to current.
- iiiears 13y agoSo in many appliances the LED serves two functions, Light and part of the active circuit to lower voltage? - This is why HN has for me replaced slashdot and digg. Thank You.
- darkarmani 13y agoA resister has a voltage drop related to the current. A diode will always drop the same voltage (within operating parameters).
