Is LED diode active or passive?

in Electrical Engineering

Is LED diode active or passive?

1 Answer

An LED (Light Emitting Diode) is an active component.

This is because it requires a power source to operate and emits light when current flows through it. LEDs are made from semiconductor materials, and when current passes through them, they release energy in the form of light. The key feature of active components like LEDs is that they control the flow of electricity and can convert energy from one form (electricity) into another (light).
