Resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. In electronic circuits resistors...

LED : Light Emitting Diode
Definition :
The light emitting diode "LED" is a 2-leads semiconductor light emitter , which emits light when a suitable voltage is applied to the leads .
The LED is the most economic light source , for example : if an ordinary lamp based on a tingesting fuse powered on 25 watt , then...
