Current and power at common voltages

Voltage	Current	Power	Resistor rating
3.3 V	2.75 A	9.07 W	over 10 W
5 V	4.17 A	20.8 W	over 10 W
9 V	7.5 A	67.5 W	over 10 W
12 V	10 A	120 W	over 10 W
24 V	20 A	480 W	over 10 W

As an LED resistor

Current through one LED in series with 1.2 Ω:

Supply	Red LED (2.0 V)	White or blue LED (3.2 V)
3.3 V	1080 mA	83.3 mA
5 V	2500 mA	1500 mA
12 V	8330 mA	7330 mA

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