Electricity Explained! Easy Study From A Physicist
When two oppositely charged bodies A and B connected by a neutral conductor, all free carriers charges under the action of an electric field begin moving towards:
• body A, i.e., a place of higher potential if they are negative;
• body B, i.e., a place of lower potential if they are positive.
The image below shows electricity explained. Such regulated (directed) movement of charge carriers is called electric current. The current disappears the moment the potentials of all bodies become equal to each other, that is when the electric field inside the conductor disappears.
The conventional direction of current is that it goes from a point with a higher potential to a point with a lower potential. However, the physical direction of the current for conductors whose electrons are carriers is from a point with a lower potential to a point with a higher potential.
You can see that such a process takes place in the conductors by the effects that accompany it.
Thus, by the enormous energy released in the form of light, heat, mechanical and magnetic, you know that lightning is short-lived, extremely strong (intense), and dangerous to humans, an electric current between clouds and the ground.
Static electricity explained
Static electricity is a type of electricity that for, unlike electricity at rest. It is defined as the charge caused by an imbalance of electrons on the surface of the material. An electron imbalance produces an electric field that can be measured and may affect other objects in the environment.
The electrostatic breakdown is the transfer of charge between bodies of different electrical potentials.
Electrostatic charge is generated in most cases by touching and separating two similar or different materials.
For example, static electricity is generated when we rub a balloon on our hair. Electricity explained with a rub.
The directional movement of the charge generates an electric current.
Necessary conditions for the generation of electricity:
- Existence of free charge carriers
- The existence of an electric field that directs free carriers
charges that are otherwise in chaotic motion
The intensity of electric current
An important measurable property of the ordered motion of free charge carriers in someone the conductor is the charge that the carriers in a unit of time transmit through the transverse press conductor.
This section of the electric current is called the strength (intensity) of the electric current. The strength of the electric current is the flow of charge achieved by orderly movement free charge carriers;
Directional movement of charge generates electricity. Necessary conditions for the generation of electricity:
- Existence of free charge carriers
- The existence of an electric field that directs free carriers charges that are otherwise in chaotic motion
All materials to a greater or lesser extent contain carriers electrification. Materials are divided based on conductivity into:
Electric current is the regulated movement of free charge carriers.
The strength of the electric current is the flow of charge achieved by the orderly movement of free charge carriers. The direction of electric current is the direction of movement of positive free charge carriers.
An alternating current is an electric current whose direction changes periodically.
An electrical source is an electrical element in which some non-electrical energy is transformed into electrical energy. An electrical consumer is an electrical element in which electricity is converted into non-electrical energy.
An electric switch establishes and interrupts the electric current in the circuit. A simple electrical circuit consists of an interconnected conductive electrical source, an electrical consumer, and a switch.
