Current and power at common voltages

Voltage	Current	Power	Resistor rating
3.3 V	485 mA	1.6 W	5 W
5 V	735 mA	3.68 W	10 W
9 V	1.32 A	11.9 W	over 10 W
12 V	1.76 A	21.2 W	over 10 W
24 V	3.53 A	84.7 W	over 10 W

As an LED resistor

Current through one LED in series with 6.8 Ω:

Supply	Red LED (2.0 V)	White or blue LED (3.2 V)
3.3 V	191 mA	14.7 mA
5 V	441 mA	265 mA
12 V	1470 mA	1290 mA

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