Current and power at common voltages

Voltage	Current	Power	Resistor rating
3.3 V	702 mA	2.32 W	5 W
5 V	1.06 A	5.32 W	over 10 W
9 V	1.91 A	17.2 W	over 10 W

As an LED resistor

Current through one LED in series with 4.7 Ω:

Supply	Red LED (2.0 V)	White or blue LED (3.2 V)
3.3 V	277 mA	21.3 mA
5 V	638 mA	383 mA
12 V	2130 mA	1870 mA

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