Current and power at common voltages

Voltage	Current	Power	Resistor rating
3.3 V	2.2 A	7.26 W	over 10 W
5 V	3.33 A	16.7 W	over 10 W
9 V	6 A	54 W	over 10 W
12 V	8 A	96 W	over 10 W
24 V	16 A	384 W	over 10 W

As an LED resistor

Current through one LED in series with 1.5 Ω:

Supply	Red LED (2.0 V)	White or blue LED (3.2 V)
3.3 V	867 mA	66.7 mA
5 V	2000 mA	1200 mA
12 V	6670 mA	5870 mA

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