Current and power at common voltages

Voltage	Current	Power	Resistor rating
3.3 V	70.2 mA	232 mW	1/2 W
5 V	106 mA	532 mW	2 W
9 V	191 mA	1.72 W	5 W
12 V	255 mA	3.06 W	10 W
24 V	511 mA	12.3 W	over 10 W

As an LED resistor

Current through one LED in series with 47 Ω:

Supply	Red LED (2.0 V)	White or blue LED (3.2 V)
3.3 V	27.7 mA	2.13 mA
5 V	63.8 mA	38.3 mA
12 V	213 mA	187 mA

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

Frequently asked questions

What are the colors of a 47 Ω resistor?

On a 4-band resistor: yellow, violet, black, gold. On a 5-band resistor: yellow, violet, black, gold, brown.

What is the SMD code for 47 Ω?

470 on 3-digit resistors and 47R0 on 4-digit (1%) resistors.

How much current flows through a 47 Ω resistor at 5 V?

106 mA, dissipating 532 mW. A 2 W resistor is enough.

Which resistors get mixed up with 47 Ω?

yellow, violet, gold, gold is 4.7 Ω and yellow, violet, brown, gold is 470 Ω: only the third band changes, so check it carefully.
