Current and power at common voltages
| Voltage | Current | Power | Resistor rating |
|---|---|---|---|
| 3.3 V | 58.9 mA | 194 mW | 1/2 W |
| 5 V | 89.3 mA | 446 mW | 1 W |
| 9 V | 161 mA | 1.45 W | 3 W |
| 12 V | 214 mA | 2.57 W | 10 W |
| 24 V | 429 mA | 10.3 W | over 10 W |
As an LED resistor
Current through one LED in series with 56 Ω:
| Supply | Red LED (2.0 V) | White or blue LED (3.2 V) |
|---|---|---|
| 3.3 V | 23.2 mA | 1.79 mA |
| 5 V | 53.6 mA | 32.1 mA |
| 12 V | 179 mA | 157 mA |
Above 20 mA: too much for a common 5 mm LED.
Standard series
56 Ω is a standard value in the E12, E24 series, so it comes in almost every resistor kit.
