⚫️ Electrical component trade
In this series of products trading training articles, we examine the trade of electrical components. Electrical parts are components of electrical devices and appliances that make them work better. There are many types of electrical parts, each of which has a specific application in electrical appliances. Among the types of electrical components, resistors, relays, switches, transistors, etc. can be mentioned.
What is an electrical component?
Electrical parts are the set of parts of appliances or electrical devices that make them work. In general, electrical parts are discrete parts that are used as the main and basic components of electrical circuits and include two terminals to connect to the circuit. For example, a lamp, fuse, car engine, etc. cannot work without electrical parts and they stop altogether. Various electrical parts in electrical appliances cause the current to be converted into another form of energy such as heat, light, movement, etc.
⚫️ How are Passive Parts?
Consumer parts that consume electrical energy and do not receive signals. Some of these parts can change the voltage, but on the other hand, they reduce the energy by losing the current. Among the passive components, we can refer to the resistors, which only consume electrical power and are not capable of generating power themselves.
⚫️ Types of electrical components and their application
Electrical components include many types such as resistors, capacitors, relays, diodes, displays, switches, etc., each of which has specific characteristics.
Resistance: Resistance is an electrical component with two heads or two terminals that reduces the current and generally limits the electric current in the circuit. Resistors are a type of parts that consume power and do not produce power themselves. There are different types of resistors and they are divided into two categories, normal or fusible, and the normal type are produced in blue, black and green colors.
Capacitor: Capacitors store electrical energy in the form of an electric field and are made of two conductive plates with an insulator between them. Capacitors are produced in different types such as ceramic and electrolytic film capacitors.
Relay: Relays are used to control electric currents, also relays are used to change low current in a circuit.
Switch: A switch is an electrical component that is used to connect or disconnect in a circuit to transfer or disconnect the electric current from one conductor to another wire. Switches have several contacts that connect them to connect the current and disconnect the contacts.
Transistor: A three-headed semiconductor device that can be voltage-controlled or current-controlled. with current voltage control
⚫️ Other electrical components
Display: This part uses two polar filters and electrodes to activate or deactivate the light. For example, the LCD display that is most used in electrical circuits, these types of displays include 2 rows and 16 columns and are called numerical displays.
Diode: A diode is a device that allows current to flow in only one direction. The diode has two terminals, anode and cathode, which are mostly used in circuits such as AC and DC.
Fuse: It is a protection piece that is used in electric circuits and its task is to protect the circuit against electric current.
Inductor: An electrical component has two terminals, which is also called an inductor, this component resists changes in electric current.
Battery: Battery is a part that converts chemical energy into electrical energy, battery is produced in different types such as low voltage and high voltage.
Power circuit: The power circuit is responsible for controlling three phases of power, that is, when it is connected, electricity flows in the circuit.
Circuit Breaker: These parts prevent the entry of excess current or short circuit.

What materials are made of electrical components?
The majority of electrical components are made of silicon. Aluminum is partially used in the manufacture of electrical components, but in modern processors copper is used more than aluminum because copper is a better electrical conductor. Another reason for using copper is the need for fine physical structures and finer connections can be made using this metal. In addition to these, another material used in making ceramic pieces is that ceramics are materials whose important part is non-conductive and non-metallic materials. Ceramic clay with capacity of plasticity and strength is used in the body of capacitor, resistor and diode. The raw materials for making electrical parts are produced by petrochemicals. In the production of these parts, the purification of raw materials plays an important role in the quality of the produced parts.
What is the difference between electronics and electronics?
There are different definitions for electricity and electronics, some people generally consider these two parts to be the same. In general, it can be said that electronics is a discipline that examines the performance of components such as capacitors, diodes, resistors, transistors, etc. Electric refers to the general set of electricity and products that are related to electricity are included in this category. Electronics is a branch of electricity, such as computers and electronic devices. Electronic devices control the movement of electrons to perform operations.
