A Resistor is an electrical component that controls the flow of electricity in an electrical circuit. Or we can say in this way that the material or component Which is used to block the flow of current in electronic equipment is called Resistor. And, because of the characteristic of the resistor or conductor that Prevents the flow of current through the conductor, that characteristic or religion is called resistance, where resistance Means the ability to block. The main function of a resistor is to cause a voltage drop to impede the flow of current in the circuit. In this case, the question may arise as to which circuit or which Parts need to be protected from low voltage or current flow.

A diode is an Electronic Device that allows current to flow in one direction only. Diode has two ends. The end where there is a line of silver color is called the cathode. The other end is called the anode. A diode basically allows current to flow in one direction and prevents current from flowing in the opposite direction. Such a tendency of current to flow in one direction is called rectification. When a circuit is connected with an anode positive and a cathode negative it is called a forward bias diode.

Light Emitting Diode (LED) Indicator lamps are a type of LED (Light Emitting Diode) lamp used to Display When a Change Occurs in an Electrical Circuit. When Something has Malfunctioned in an Electrical System, a red or Orange Light Emitting Diode Indicator Lamp may be used to alert a Worker. LED Indicator Lamps Usually consist of a single Bulb. Pilot lights and Light Emitting Diode indicator lights Indicate Lights for Machines or Instruments and they can also be built into Switches. They Provide Solutions for a Variety of Requirements and Are ideal for Highly Reliable Indications.
