Need help with a Resistor calculation please
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. 1kΩ b. 500Ω c. 350Ω d. 100Ω |
