The invention of electricity is one of the most important inventions that humanity has witnessed, as electricity is an essential part of our daily lives, and it has made it easier for people to do many tasks that were previously manual work. Before electricity was discovered, the process of washing clothes was done manually, and after the invention of electricity Electric washing machines were available that saved effort and time, in addition to the invention of electricity paving the way for more discoveries such as the iron, the lamp, and the broom.

What is electric current

Electrical current from power stations reaches homes, factories, institutions, hospitals, etc. It is defined as a stream of negative electrical charges that move regularly and in a specific direction. The electrical current cannot be seen, but its effect can be felt in operating electrical appliances.

Materials are divided in terms of their ability to transmit electrical current into conductors, which are materials that allow electrical current to pass through them, such as copper wires, and insulators, which are materials that do not allow electrical current to pass through them, such as ebonite rods and plastic sheets.

Effects of electric current

Since electric current cannot be seen with the eye, its effects appear clearly in life, including:

The thermal effect, which means the passage of electric current through the wires, which leads to an increase in the temperature in them. This confirms the thermal effect of electricity, which has been used by scientists in many applications, and resulted in the manufacture of the electric stove, iron, electric heater, electric lamp, and other inventions.

The luminous effect: Electric current has a luminous effect as it spreads light when it passes through lamps that contain noble gases, such as neon gas. A neon lamp glows with light when an electric current passes through it, and it does not contain a wire that heats up and then lights up like an electric lamp with a wire.

The magnetic effect. Physicists have proven that electricity has a magnetic effect when a compass was placed and its needle was left until it stabilized. Then they placed a wire over the needle parallel to it, with both ends of the wire connected to a dry battery and a circuit breaker. They noticed that when the circuit breaker was closed, the needle deviates from its original position. This confirms Magnetic effect of electricity.

The chemical effect: when an electric current passes through a solution, this leads to the disintegration of the solution into its components, so this application is used in plating operations. Scientists found that when two plates of platinum were dipped in a solution of concentrated sulfuric acid in a glass bowl and then connected the two plates to a source of electric current, There will be gas bubbles around the two plates, and after analyzing what the bubbles are, it turns out that they are oxygen gas and hydrogen gas, forming water.

How to avoid electrical damage

Electricity is a number of very small molecules or particles that are not visible to the naked eye. They have a continuous movement that does not stop except by storing them in one of the types of dry or non-dry batteries or by cutting them off with a button or electrical wire. Electricity expresses the movement of electrons or charged particles through wires. Minerals, and electric current is only the result of the flow of electricity, and electricity is the source of energy that many electrical devices need. Without electricity, we would not be able to watch television, for example, or use the Internet, or use many of the things that we are accustomed to in our lives.

The human body is also considered a conductor of electricity, as the cells of the human body are a factory that does not stop vital processes through the cell wall, which represent an electrical voltage, which is the basis of cell life and human life. Since the human body is a conductor of electricity, it is exposed to many electrical accidents that may lead to electrocution. Or burns. Although electricity is very beneficial to humans in their practical lives, caution must be exercised while using electrical devices.

Many painful accidents occur due to electricity, and the extent of damage resulting from electrical accidents depends on the duration and path of the electrical current, and depends on the degree of the body’s resistance to electricity.

Ways to prevent electrical hazards

Avoid operating electrical appliances when the body is wet with water.

Avoid disconnecting devices from the electrical outlet by pulling the wires.

Avoid touching bare wires or using them to operate electrical appliances.

Avoid using any electrical device that has been partially immersed in water.

– Ensure that the tension of the device to be operated is compatible with the tension of the electrical plug before connecting them to each other.

– Providing homes with safety devices from the dangers of electrical current, such as a regular separator, differential separator, and ground connector.

Installing electrical outlets in places away from children.

Use separators and fuses to protect household structures from any damage that may cause fires.

Connecting the metal structures of electrical appliances to electrical plugs connected to a grounded connector.

Pay attention to installing special covers for electrical sockets to protect children.

Connect the neutral wire of the ground conversion center to a ground clamp to protect the electrical lines from ground lightning.

Avoid using water with electricity, as it constitutes a big step, and its effect may be fatal. It is preferable for the electrical source to be connected to an automatic ground breaker via one of the compressors.

Avoid overloading any electrical compressor. In addition, if you feel heat in the switches or electrical connections, you must inform the specialist to do so.

Avoid carrying out any electrical repairs unless an electrical specialist is present.

Avoid touching any electrical device with one hand while touching another electrically conductive material with the other hand, such as a water pipe.
