Electrical properties


Electricity gave rise to the 4 fundamental forces of nature, and its remains in objects can be measured. In this case, the phrase "the amount of electricity used also with the phrase" electrical charge "as well as" the amount of the charge ". There are 2 types of electric charge: positive and negative. Through experiments, payload-a kind of mutual refused and charge-opposite sex attracted to each other. The magnitude of this style is exciting and rejecting established by Coulomb. Some of the effects of power discussed in electrical and electromagnetic phenomena.

The SI unit of electric charge is the coulomb, which has stood for "C". The symbol Q is used in the equation to represent a quantity of electricity or charge. For example, "Q = 0.5 C" means "the quantity of electric charge is the coulomb 0.5".

If the electricity flowing through the special materials, such as tungsten and tungsten, of light emitted by metal will flare it up. Such materials are used in a light bulb (bulb or bulblamp).

Whenever electricity flows through materials which have barriers, it will be hot removed. The greater the flow of electricity, then the heat arising will be doubled. These properties are used on elements of irons and electric stove.

What is Electricity

Electricity is the nature of objects that arise from the presence of electric charge. Electricity, can also be interpreted as follows:

Electricity is the condition of certain subatomic particles, such as electrons and protons, which led to the withdrawal and rejection of styles in between.
Electricity is a source of energy that is transmitted via cable. Electric current arises because the electric charge flows from positive to negative channels channels.

Along with magnetism, electricity form the fundamental interaction is known as electromagnetism. Electricity allows the occurrence of many physical phenomena which are widely known, such as lightning, electric field and electric current. Electricity is widely used in industrial applications such as electronic and electrical power.

Thermal energy storage


Thermal energy storage is temporary energy storage or removal of heat for use at a later date. Thermal energy storage that are common at this time is useful for ice storage move heat when needed. Ice is made at night when peak loads. This method is recommended and developed by the u.s. Green Building Council's Leadership in Energy Efficiency program and Environmental Design to arouse the development of building design-capable high that is safe for the environment.

The advantage of making ice at night include: after passing the peak load electricity have lower fees so that cheaper, and energy to cool the ice on a cold night is faster and requires less energy, so the ice can be produced in an amount more. It can be said that in this way, a lot of energy from the power plant was saved while more energy is released from storage for some time.

Energy is not always can be taken

Energy storage


Many renewable energy as a source of energy which cannot always be utilized because a limitation (solar energy, wind, etc.), but can be used to fill in the supply of energy while other sources of energy are stored for use on electric transmission network, or the energy source used to fill out the electrical system network when required. If the loss of energy when the distribution and costs can be set, then this type of energy can become a mainstay.

Solar energy, even though it currently cannot be used throughout the day, but currently have designed solar energy satellites are useful for capturing the energy of the Sun via satellite through outer space and didstribusikan to Earth in different ways so that the solar energy utilization can become longer with the amount of energy taken bigger (because the Sun's energy in space greater than solar energy that has touched the surface of the Earth).

Energy storage methods

Energy storage methods

Mechanical storage

Energy can be stored by pumping water up to a certain height and released into electrical energy when needed.

Pressurized air is a cheap energy storage method using electrical energy cheap while being not happening peak loads. Pressurized air can be stored in underground reservoirs. The pressurized air is then released when peak loads for supplying electric energy and can be heated using the heat removed by machines or electric generators to increase the pressure.
