What is Resistor?

A Resistor is an electronic component that limits/resists/regulates the flow of electric current in electronic circuit. resistors can also be used to provide a specific voltage for an active device such as a transistor.

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:
