I have this question and I am wondering if someone can tell me the formula and how they derived the answer (steps) - it is probably simple, but I am learning this as I go :
Electronic
1) A simple circuit consists of a current limiting resistor in series with an LED across a supply voltage of 5VDC. The forward voltage drop is 1.5VDC and the forward current is 10mA. The series resistor would have a value of: a=2E 1k=CE=A9 b=2E 500=CE=A9 c=2E 350=CE=A9 d=2E 100=CE=A9
