Frequently asked questions
Can I use a 510 Ω resistor to limit LED current on a 5 V supply?
Yes, 510 Ω is a common value for a standard LED on a 5 V supply. The exact current depends on the LED's forward voltage, so calculate (Vsupply − Vf) / R before final use.
Is a 1/4 W rating enough for my circuit?
A 1/4 W resistor can dissipate up to 0.25 W. Calculate the power as P = I²R or V²/R and keep it below this rating with some margin.
