Nettet13. nov. 2024 · Normal automotive system voltage is about 12.6 volts and when the engine is running about 13.6 volts or slightly higher. Automotive LED design headlights are designed around this. They should work fine anywhere between 12 volts, maybe a little less right up to 14 volts or slightly higher. NettetJust use the standard resistor values chart to find the nearest highest value available. Example 1: The blue LED has a typical forward voltage drop of 3.2 V, therefore a 5 Ω resistor is required when using a 3.3 V supply voltage. However, if you are using a 5 V supply voltage, then a 90 Ω resistor is needed. As you can see, the resistor ... holden rg colorado workshop manual

The appropriate value for the pull-up (or pull-down) resistor is limited by two factors. The first factor is power dissipation. If the resistance value is too low, a high current will flow through the pull-up resistor, heating the device and using up an unnecessary amount of power when the switch is closed. holden recallsNettetIf they list a range ("20-30mA") pick a value in the middle (25 in this case).
