What is LED?

A light emitting diode(LED) is a semiconductor device that emits light when an electric current flows through it.     LED is a light source. It has two terminals, longer one is positive and shorter one is negative. Positive terminal of the LED connect with positive of the battery. Negative terminal of the LED connect with negative of the battery.                                                                                                                                                                              Symbol of LED:

What is Linear Voltage Regulator?

 A Linear Voltage Regulator is an electronic component that is used to reduce and maintain constant voltage in a circuit. There are different types of voltage regulator ICs for different different uses like 7805 IC is used for 5 volt constant output,        7806 IC is used for 6 volt constant output,        7808 IC is used for 8 volt constant output,        7809 IC is used for 9 volt constant output,        7812 IC is used for 12 volt constant output,        7815 IC is used for 15 volt constant output,        7818 IC is used for 18 volt constant output,        7824 IC is used for 24 volt constant output, Thanks👍 👉 Follow us on Instagram 👉 Follow us on Facebook 👉 Follow us on Twitter 👉 Follow us on LinkedIn

What is Transistor?

Transistor is a three terminal electronic component that is used to amplify the electric signal as well as used as a switch. Real view of transistors: Symbol of transistor:  E = emitter                                                       B= base                                                              C= collector                                  Terminal identification of transistor:                                                                 It depends on value and type of transistor. NOTE: It's also made of semiconductor materials. There are many type of transistor . It's use as a switch. It's use as a amplifier.
