Current and power at common voltages
| Voltage | Current | Power | Resistor rating |
|---|---|---|---|
| 3.3 V | 44 mA | 145 mW | 1/2 W |
| 5 V | 66.7 mA | 333 mW | 1 W |
| 9 V | 120 mA | 1.08 W | 3 W |
| 12 V | 160 mA | 1.92 W | 5 W |
| 24 V | 320 mA | 7.68 W | over 10 W |
As an LED resistor
Current through one LED in series with 75 Ω:
| Supply | Red LED (2.0 V) | White or blue LED (3.2 V) |
|---|---|---|
| 3.3 V | 17.3 mA | 1.33 mA |
| 5 V | 40 mA | 24 mA |
| 12 V | 133 mA | 117 mA |
Above 20 mA: too much for a common 5 mm LED.
Standard series
75 Ω is a standard value in the E24, E48, E96 series. Check the tolerance and power rating of the actual component.
