Frequently Asked Questions
AI
Yes, most LEDs require a current-limiting resistor to prevent them from burning out. Without one, the LED may draw too much current from the power source, leading to permanent damage.
The primary difference is the physical size of the diameter. 5mm LEDs are generally more common for breadboard prototypes and are easier to handle, while 3mm LEDs are better for compact designs.
LEDs are polar components, meaning they have a positive (anode) and negative (cathode) side. If connected in reverse, the LED will not light up, but it typically won't be damaged unless the voltage is too high.
