Electrical circuit componentsnada shaban
Perhaps many people think when turning on any light, what is the reason behind this light, and what made the light shine like this, and many do not know that light needs four basic parts, which are called electrical circuit components, and these components work to provide the necessary energy that works. To produce light, or operate many electrical devices.
What is an electrical circuit?
An electric circuit is a closed path. This path transmits electric current amidst electric and magnetic fields. For example, the electrons enter the circuit through the so-called source, which is a battery or a generator. This source provides energy to these electrons, by creating an electric field. These electrons leave the circuit through the load, in order to complete a closed path. The load can be on any simple home appliance such as a television, lamp or refrigerator, or it can be a complex load such as the one in a hydroelectric power station.
Electrical circuit components
- power source
- the key
Every electrical circuit, regardless of its size or location, contains basic components, which are the power source, the connector, which is a wire, the electrical load, which is the device, and the control unit, which is the electrical switch. Any turning on of a light leads to the flow of electricity, and this must be done through The wiring of the electrical system, and it converts electrical energy into visible light. For example, this process is used to operate devices such as computers, televisions, or any electrical device.
Power source: In an electrical circuit, the power source provides the necessary power and voltage. This voltage is what pushes the electrons through a conductor, and is measured in volts to activate the device connected to the circuit. The power source provides a constant voltage for the electrical circuit. Examples of voltage power sources include batteries such as those found in a computer. Mobile phone or car, or energy coming from solar panels or hydroelectric dams, and the power source for the electrical circuit means the constant current source, and it is measured in amperes.
Conductor: In any typical environment that operates with electricity, we find the conductor in electrical devices is the wire that provides the path of the electrical circuit, through which energy flows, and the conductor connects all other parts of the electrical circuit, and the conductor provides the pipes through which electrical energy flows, such as water flows from Through hose.
Switch: The switch in the electrical circuit provides control of closing or opening. There are a variety of electrical circuit switches. Examples of these switches include wall switches, push buttons, and toggle switches. These switches allow a continuous flow of power and provide transient, or instantaneous, communication. You have to press play button or device.
Load: Any device connected to the electrical circuit is energized and provides an electrical load on the electrical circuit. Load is the amount of electrical energy that the device uses to complete its task. This electrical consumption is measured in watts, which is equal to amps. Lamps, televisions, motors, and heaters are For load devices that consume energy. 
Other electrical circuit components: While most electrical circuit components are three or four basic components, we find that there are other components that can be included in the electrical circuit components, and examples of other components include gates, hinges, transistors, and counters of different types.
Active electrical circuit elements
There are many active elements that generate energy. Examples of active electrical circuit elements include batteries, generators, and operating amplifiers. The power source is considered one of the most important active elements in the electrical circuit, and the power source, whether it is a voltage source, or a current source that is an independent source, or a dependent source. An example of an independent source is a battery, which provides a continuous voltage to the electrical circuit. An example of a dependent source is a transistor, which provides a current to the electrical circuit depending on the applied voltage.
Negative electrical circuit elements
Negative electrical circuit elements are elements that can control the flow of electrons, either increasing the voltage, or decreasing the voltage. Examples of negative electrical circuit elements include:
Resistor: The voltage across a resistor is directly proportional to the current flowing, and opposes the flow of current through it.
Induction: Induction stores energy in the form of an electromagnetic field, and the voltage across the inductor is proportional to the rate of change of the flowing current.
Capacitor: The capacitor stores energy in the form of an electrostatic field, and the voltage across the capacitor is proportional to the charge.
Facts about the electrical circuit
- Electrons enter at a certain point into an electrical circuit called the “source” of electrons, and these electrons always end up at the source when they complete the path of the electrical circuit.
- The part of the electrical circuit located between the starting point of the electrons and its ending point to the source is called the electrical circuit. The load of the electrical circuit may be simple as it powers electrical appliances such as refrigerators, televisions, or lamps.
- Electrical circuits use two forms of electrical energy, alternating current and direct current. Alternating current powers appliances, large motors, and is created by power plants. Transformers can change alternating current to DC, and vice versa. High-voltage direct current bus uses large transformers very.
- Transistors act as switches and amplifiers in most electronic circuits. Designers often use a transistor as a toggle switch, because unlike a simple switch, it can convert a small current into a much larger current. Although you can use a simple switch in a regular circuit, you need the advanced circuit. Which gives you varying amounts of current at different phases.
- Electrical circuits typically use low-voltage direct current sources. The electrical circuit may be simple with a few resistors, capacitors, and an LED. The electrical circuit can be complex, connecting thousands of resistors and capacitors, and it may be an integrated electrical circuit such as a processor in a computer.
Symbols of electrical circuit components
Circuit diagrams and schematic diagrams are a simple and effective way to show the electrical connections, components and operation of a particular circuit or electrical system. Basic electrical and electronic graphic symbols called schematic symbols are commonly used in circuit diagrams, schematics, and computer-aided drawing packages to identify the locations of individual components and items within a circuit.
Graphical symbols not only identify the location of components, but also what type of electrical item it is, Thus in circuit diagrams and diagrams, graphic symbols identify and represent electrical and electronic devices, showing how they are electrically connected to each other while drawing the lines between them representing the wires or leads of the components. The following image shows the most important symbols Electrical circuit components:
The function of connecting wires in an electrical circuit
Conducting wires provide a medium for electrical current so that it can travel from one point in a circuit to another, example in the case of computers, wires are embedded in circuit boards to transmit pulses of electricity.
In a basic circuit, a wire comes from one end of a power source, and is then connected to a switch that determines whether the circuit is open or closed. Wires connected to a device are used to draw power and electricity, and perform specified tasks. Before current can travel through the wire, the circuit must be closed. It cannot If there are any breaks in the path, electricity cannot easily travel through the air, and if it does, there is a risk of a stray current leaking into the surroundings and causing damage to the device or failure to operate.
