Light Emitting Diode (LED)
I briefly alluded to LEDs in the scenarios that were used under “Resistors” above. LEDs are just like bulbs except that they are extremely reliable. You can find them on practically every appliance in your home that features some kind of an indicator light. A typical LED bulb can last decades with no sign of dying.


Since they are so reliable, they are used to indicate the state of current at any point in a circuit. An important task like checking the output voltage or current on a circuit becomes simpler with these light-based indicators.
