Can I use 100 Ω to limit current for an LED?
It depends on the supply voltage and the LED's forward voltage and current. Use I = (Vsupply − Vf) / R to confirm the resulting current is within the LED's rating.
Is a 1/2 W rating enough for this resistor?
Yes, as long as the power dissipated stays below 0.5 W. Calculate P = I² × R or P = V² / R for your circuit.
