Hi there!
Here's the answer:
LED - Light Emitting Diodes.
Two terminals - cathode and anode.
For an LED to glow, the terminals should conduct electricity within the terminals.
This Conducting voltage is Very less for an LED. This voltage is called cut-in voltage.
Cut in voltage for an LED = 2.5 v
When the terminals has 2.5 volts, this LED conducts and stars to glow.
If it exceeds a certain higher voltage, it may result in breakdown of LED.
:)
Hope it helps
