Current and power at common voltages

Voltage	Current	Power	Resistor rating
3.3 V	84.6 mA	279 mW	1 W
5 V	128 mA	641 mW	2 W
9 V	231 mA	2.08 W	5 W
12 V	308 mA	3.69 W	10 W
24 V	615 mA	14.8 W	over 10 W

As an LED resistor

Current through one LED in series with 39 Ω:

Supply	Red LED (2.0 V)	White or blue LED (3.2 V)
3.3 V	33.3 mA	2.56 mA
5 V	76.9 mA	46.2 mA
12 V	256 mA	226 mA

Above 20 mA: too much for a common 5 mm LED.

Frequently asked questions

What are the colors of a 39 Ω resistor?

On a 4-band resistor: orange, white, black, gold. On a 5-band resistor: orange, white, black, gold, brown.

What is the SMD code for 39 Ω?

390 on 3-digit resistors and 39R0 on 4-digit (1%) resistors.

How much current flows through a 39 Ω resistor at 5 V?

128 mA, dissipating 641 mW. A 2 W resistor is enough.

Which resistors get mixed up with 39 Ω?

orange, white, gold, gold is 3.9 Ω and orange, white, brown, gold is 390 Ω: only the third band changes, so check it carefully.
