LEDs can be powered using a DC power source. Simply connect the positive lead of the LED to the positive terminal of the power source and the negative lead to the negative terminal. Ensure the voltage matches the LED's rating or use a resistor to prevent damage.

FAQs & Answers

  1. What voltage do I need for my LED? The voltage required for an LED varies, typically between 2V to 3.6V, depending on the LED type. Always check the specifications.
  2. Can I use any power source to power my LEDs? No, you need a compatible DC power source that matches the voltage rating of your LED to avoid damage.
  3. What is the purpose of using a resistor with an LED? A resistor limits the amount of current flowing through the LED, protecting it from excessive current and potential damage.
