Types of electricity: static and dynamic

Types of electricity: static and dynamic

Electricity is the set of physical phenomena related to the presence and flow of electric charges.

The movement or flow of electrons produces this form of energy. Electrons are tiny particles in atoms. The movement of electrons causes an electrical charge or voltage that releases energy.

Electrons are subatomic particles that revolve around the nucleus of an atom. They have a negative charge, and if they experience a force of attraction or repulsion, they can move from one atom to another of a conductive material. Generating electricity means generating this movement of electrons.

There are two types of electrical energy:

  • Static electricity is a type…

What is electricity?

What is electricity?

Electricity is the set of phenomena caused by the existence, interaction, and motion of electric charges. It is the energy derived from electric potential energy or kinetic energy.

This form of energy manifests itself in charged particles’ movement on the surface of a conductive material. The charged particles can be electrons, protons, or ions.

There are two points of view to analyze it:

  • From a macroscopic scale: what a person can observe.

  • From a microscopic scale: to observe what is happening, it is necessary to use special devices. The set of things that happen on a tiny scale corresponds to what we can see on a macroscopic scale.

Static electricity. Definition and examples

Static electricity. Definition and examples

Static electricity is an imbalance of electrical charges in a material.

Materials are made up of atoms with charged particles. Atoms are made up of neutrons and protons in the nucleus and electrons around it. Protons are positively charged and neutrons negative. An atom has the same number of positively charged protons as negatively charged electrons.

Imagine we have two conductive materials (A and B). Material A and material B are very close; the electrons can jump from one material to another. For example, from A to B. Material A loses electrons, and B gains them.

The result of this electron transfer is that Material A will have more protons than electrons. That is,…

What is thermical energy?

What is thermical energy?

Thermal energy is the energy released in the form of heat. It manifests itself by releasing heat. It results from the atoms’ movement or vibration, so it displays the system’s internal energy.

We define thermal energy as part of the internal energy of a system. The internal energy is proportional to its absolute temperature and increases or decreases by energy transfer.

Increasing the thermal energy of a body, its molecules move faster.

Energy is measured in Joules (J) according to the SI of measures. However, when it comes to heat energy, calories (cal) are also often used.

Examples of thermal energy
  • In boiling water, we are transferring…

Phases of photosynthesis

Phases of photosynthesis

The process of photosynthesis is carried out in stages in two stages:

  • The light-dependent stage (or light stage);

  • The carbon fixation stage of which the Calvin cycle is a part.

Plants, algae, and cyanobacteria are photosynthetic organisms. Photosynthesis occurs inside plant cells in small objects called chloroplasts. 

Chloroplasts contain a green substance called chlorophyll. The chlorophyll from the green plants absorbs the light energy needed to make photosynthesis happen. 

Stage one of the photosynthesis: Light Reactions

The light stage is a biological process in which energy from sunlight is converted…

Questions about solar energy

Questions about solar energy

Solar energy is a renewable energy source that in recent years has gained considerable strength as an alternative to fossil fuels.

The simplicity and advantages of solar energy offer many installation possibilities to small producers. However, before considering the feasibility of such an investment, many questions about solar energy may arise.

Below we will try to resolve some of these doubts.

Are solar thermal and photovoltaic installations compatible?

Photovoltaic modules capture photons from sunlight and produce electricity. Solar collectors take advantage of solar heat to obtain sanitary hot water. In the same installation, both solar energy systems are compatible.

What is and how does a geothermal heat pump work?

What is and how does a geothermal heat pump work?

The geothermal heat pump is an air conditioning and heating system for buildings that exploits the heat exchange with the surface subsoil. In this case, the exchange is carried out by means of a heat pump.

Since the heat from the ground largely from within the Earth, low-temperature geothermal energy is classified as a renewable energy source. 

The heat pump allows transferring heat from a cold source to a hot source. In a heating system, the building represents the hot spot. In an air conditioning system, the building is the cold source from which the heat is drawn.

According to the second law of thermodynamics, heat is only transferred from a hot bulb to a cold…

What are the advantages and disadvantages of geothermal energy?

What are the advantages and disadvantages of geothermal energy?

Geothermal energy is a renewable energy. Its origin is in the heat stored inside the Earth. This clean energy is transmitted through hot rock bodies or conduction and convection.

There are two types of geothermal energy types:

  • Small facilities. This technology can be used to obtain sanitary hot water. It is also used in heating systems. It is frequent to see it installed in homes.

  • Large geothermal plants. These plants convert geothermal resources into electricity.

The use of geothermal energy implies the following advantages and disadvantages:

History of solar energy

History of solar energy

Throughout history, solar energy has always been present in the life of the planet. This source of energy has always been essential for the development of life. Over time, humanity has increasingly improved the strategies for its use.

The Sun is essential for the existence of life on the planet. It is responsible for the water cycle, photosynthesis, etc.

First civilizations realized this and developed techniques to harness their energy have also evolved.

At first they were techniques to harness passive solar energy. Later techniques were developed to take advantage of solar thermal energy from the sun's rays. Later, photovoltaic solar energy was added to obtain electrical…

Internal energy in thermodynamics

Internal energy in thermodynamics

In thermodynamics, the system’s internal energy is called the total energy that a system contains. 

This energy can be modified by exerting work on it or by the transfer of energy. The system’s energy can change by transferring heat or work (or both) between the system and its surroundings. If positive work is applied, the system gains energy.

The first law of thermodynamics postulates that the increase in internal energy is equal to the total heat added plus the work done by the environment. If it is an isolated system, it remains constant.

Internal energy is a state function. Its value depends only on the current state of the system. It is also an extensive…

What does hybrid solar energy mean?

What does hybrid solar energy mean?

Hybrid solar systems are hybrid power systems that combine the photovoltaic system with another energy source of energy. However, the term “hybrid solar panels” refers to solar and battery storage which is connected to the electricity grid.

Hybrid solar systems generate power in the same way as a common grid-tie solar system. The most common combinations of hybrid solar energy are:

  • Use of diesel generators. They are heat engines that use derivatives of fossil fuels. Therefore it is a non-renewable energy source.

  • Use of wind power generators. Wind power is also intermittent but it can be complemented quite well with solar.
