The origin of the electricity: Electricity is the form of energy that arises from physical phenomena associated with stationary or moving electric charges. More specifically, the movement of electrons in the outer shell of atoms in a conducting material.
ELECTRICITY
Electric current is the orderly movement of electrons from a negatively charged body to s positively charged body.

The electric current travels along a closed path that is called an electric circuit What is an Electrical Circuit? An electrical circuit is a path through which electric current can flow from a power source, such as a battery or a generator, passing through various components, and returning to the source. The flow of electric current depends on the circuit being closed, meaning there are no interruptions. Basic Elements of an Electrical Circuit: Power Source: A power source, like a battery or a generator, provides the necessary energy for electrons to flow through the circuit. Conductors: These are wires or materials that allow electric current to pass through. Copper is the most common conductor material. Electric Loads: These are devices that consume electrical energy and convert it into other forms of energy, such as light, heat, or motion. Examples include light bulbs and motors. Switch: A component that can open or close the circuit, controlling the flow of current. For example, switches that turn devices on or off. Resistors: Components that limit the flow of current, creating resistance. They help control the amount of current in the circuit.

Types of Electrical Circuits: Series Circuit:In this type of circuit, components are connected one after the other. If one component fails, the entire circuit is interrupted. The current is the same at all points, but the voltage is divided among the components. Parallel Circuit:Components are connected in separate branches. If one component fails, the others will continue to function. In this type of circuit, the voltage is the same across all branches, but the current is divided among them. Basic Operation of an Electrical Circuit:When the circuit is closed, the electrons in the power source (like a battery) begin to move through the conductors, creating an electric current.This current passes through the electric loads (such as a light bulb), where it is converted into light or heat, depending on the device.The switch is used to open (disconnect) or close (connect) the circuit, controlling when electricity flows. When Do We Use an Electrical Circuit?Electrical circuits are found in nearly all electrical and electronic devices we use daily, such as lights, televisions, computers, electric motors, and industrial applications.In Summary:An electrical circuit is the infrastructure that allows electricity to flow and be used in devices, providing energy to the loads that need it.
According to Ohm's law, the electric current in a circuit is directly proportional to the voltage or tension and inversely proportional to the circuit's resistance
R=V:II=V:RV=I·R
R=resistance
I=inversely
V=voltage
Ohm's law
3.electrical magnitudes
Circuits are formed by connecting several receivers,which can be different elements ,such as lamps ,motors,etc.
4.Combinators of resistors
Relays are switches that can be electromechanically actived either by means of an electromagnet or based on a semiconductor's properties.
Electronic circuits are responsible for the control, management and distribution of electrical signals. They consist of components, such as resistors, coils, capacitors a nd components called semiconductors, such as diodes, transitors integrated circuits.
5.INTRODUCTION TO ELECTRONICS
Waste electrical and electronic equipment or WEEE is all equipment that requires electrical current or elctromagnectic fields to operate, as well as its accessories and consumables.
