  • I’m still relatively new to electronics and have a question. When talking about the LED you mentioned:
    “You may be wondering if the resistor/LED order matters. It does not. The resistor can come first and then the LED or as shown. Either configuration will correctly limit current through the LED."
    Why is this so? I don’t understand why you can put the resistor on either side of the LED. Wouldn’t the resister need to come before the LED to resist the flow of power into the LED? How does it help afterwards when the power has already gone through the LED?

No public wish lists :(
