Electricity was discovered in the late 19th century. It has become one of the basic services in life due to its multiple uses and applications in various aspects of life. It is one of the forms of energy that results from the presence of elementary particles carrying various electrical charges, such as electrons and protons. Electricity arises as a result of the accumulation of charges or the movement of electrons, especially their flow in the conducting body, and this is called current. Whereas electrons are negatively charged particles, and protons are positively charged particles.

The importance of electricity:

Its importance lies in its multiple uses, such as lighting, which is a necessity for the progress of society and the prosperity of its economy. Its presence facilitates life and makes it safer and more secure for individuals. Electricity keeps homes cool through air conditioning devices, or warm through safe heating devices. Moreover, through electrical appliances, an individual can protect food from spoilage by placing it in the refrigerator, for example, and obtain pure water for drinking and daily use. Hence, it can be said that electricity is of indispensable importance to individuals, whether at home or in the establishment.

Risks:

Despite the great importance of electricity in our daily lives, this importance lies mainly in facilitating the means of life and saving time and effort when performing the tasks that the individual must master. However, when we use electricity, we must be careful of many risks, which include the following:

• Causing short circuits, electric shocks and burns to the human body upon contact.
• Fires occur when there is a defect or error in the connection.
• Causing electrical explosions when there are electrical wires in a flammable environment.

It is also necessary to point out that the extent of the danger of electricity and the resulting damage depends on both the way the individual uses electricity. For example, it is forbidden to connect electrical wires in damp or wet places because this poses a strong danger to those around them. It may cause electrical short circuits and cause individuals to suffer electric shocks, etc.

Electricity services:

Electricity services vary according to the benefit that the members of the home or facility receive. For example, individuals benefit from electricity for lighting by using various electricity services such as lighting lamps, chandeliers, etc. Services in both homes and establishments include the following:

• Lighting lamps: The lighting lamps service consists of installing and replacing them by providing different styles to lighting designers regarding the types of suitable lighting lamps of all colours, sizes and shapes to suit the décor of the place.
• Chandelier: This service includes installing and replacing the chandelier (chandelier), as long as it is not exposed to any scratches during installation or replacement.
• Electrical sockets: The service consists of the electrician installing or replacing the sockets with the necessary wiring extensions when needed.
• Suction and ventilation fans: This service consists of installing or maintaining both suction and ceiling ventilation fans of various types, with the necessity of making the necessary wiring extensions to complete the implementation of this service.
• Voltage level conversion: regulating the voltage of the place so that it is converted from 110 volts to 220 volts; This is in order to provide a constant voltage to the system’s capacity in different load cases.
• Electrical wires: The electrical wiring service includes extending or maintaining new electrical wires according to the service provider’s inspection of the work, in addition to the electrical engineer or technician’s knowledge of the electrical connection feature, the types of electrical wires and their uses, as well as determining which electrical wires are most appropriate according to the use and features of each.
• Electricity distribution panels: This service includes installing or inspecting distribution panels, whether solar panels or batteries, or maintaining electricity distribution panels and breakers.
• New electrical installation: This service includes establishing new electricity for the rooms or renewing the current installation, as well as extending electrical wires according to the distribution designed by the home’s electrical engineer, and installing all of the electrical sockets and switches necessary for the rooms of the house so that the distribution of electrical sockets and switches matches the room’s décor.
