Introduction
The circuit stands defined as the path by which the power is transmitted, including conductors or power transmission lines, electrically generating devices for charged particles that make up the electric current, such as a battery or generator.
Electrical power-consuming devices, such as lamps or electric motors, computers. And um and Kircher’s laws explain the mechanism of operation of the circuit.
Circuit Components
There stand four main parts that should be available in any circuit, no matter how simple: Power Source stands for the part that provides the energy needed to transport electricity through the course and is chosen based on voltage requirements, such as battery and electrical exits. Electric load is a device that consumes energy. And the circuit stands designed to operate it, such as a simple light bulb. Wires are copper or aluminum wires used to transport power efficiently. And lose the least energy during the transfer. Electric
Key
The device opens and closes the circuit without separating the wires from any component, called the circuit where the electrical key stands closed. All cables are connected and transmit electricity in all parts (closed circuit). In contrast (an open circuit) is the circuit where the key stands open. Or the wires are not connected.
Circuit Elements
They are classified into two categories:
Active Elements are the elements capable of delivering power to the circuit by converting energy from non-electric to electric power sources, such as the battery, as chemical energy converts into electric power.
And the solar cell converts solar energy into electric power, in addition to the transistor, the diode valve. Ineffective elements: (Passive Elements), unlike active elements, consume electric power instead of supplying the circuit, such as electrical resistance, condenser, and inductor (electrical file).
Battery
The battery is one of the primary sources on which the circuit depends to operate. The electric power produced by converting chemical energy into electric power pushes the current through the course. It is worth noting that different batteries can connect respectively for more effort.
Wires
The importance of wires is that they connect all the circuit components, and the current flows easily through it until all elements of the circuit work. These wires must make low-voltage electrical conductors, and copper and aluminum stand the most commonly used conductors in the wire industry. In contrast.
Resistance
The resistance stands called a resistor because it resists the flow of current. Some elements in electronic devices are susceptible to the electric current and can burn if the flow of the recent increases suddenly.
Here comes the role of the resistor, as the resistance prevents the increase in the flow of current, so resistance is an essential element in the circuit, with little resistance, high conductivity. And low resistance metals such as silver. And copper allows electrons to move freely between atoms.
Therefore, the number of resistances needed to place in the circuit depends on the value of the flowing current to stand resisted. And the greater the resistance, the greater the circuit’s ability to resist the current
Electric Condenser
The capacitor stands as the second most commonly used component in circuit design, similar to its battery mechanism, used to store electrical charge, consisting of two flat conductive panels separated by a small gap.
The voltage difference between the two panels is proportional to the different amounts of charge on them. And the capacity of the capacitor stands measured by the microfarad “μF,” which can express in the mathematical equation
Induction
So, the inductor stands a roll of wire used in many circuits. And its magnetic field stores the energy generated by the flow of electricity during it. And it is worth noting that only direct current (DC) stands allowed to pass through it. At the same time, ac stands prevented from passing and stands used in filters to separate signals at different frequencies.
Therefore, it stands often used in active courses that allow low-frequency oscillations to pass while blocking high-frequency signals. The integration of inductors into the same trajectory leads to the filtration or generation of fluctuations at any required frequency.
