What is the electric power?
Four forces are understood to control the universe: strong and weak nuclear forces, electromagnetic - or electric - forces and gravity. The latter two types, electric strength and gravity are the only one of these forces that reach the macro range and therefore interact with a large scale matter. Electromagnetism is responsible for chemical reactions, light, vision and virtually all the interplay of matter. Almost all technology requires the functioning of electricity and there are several vital aspects and measuring electricity. The basis of this force is the movement of electrons and the functioning of positive and negative electrical cartridges. The protons that form the core of the atom have a positive charge, while the electrons that circulate the core have a negative charge. The opposite fees attract each other in an effort to neutralize the charge and, as well as forgiving the fees of the two magnets, together cause the ends of the magnets to attract each other. Electricity in its most basic form is the movement of electrons from one placeon the other in a static discharge or in an electronic district; Electricity can only flow where the conductive path is available.
The electromagnetic force is thus named because the electrical current and the magnetic field can create each other. Walking through the magnet through the wire coil causes the electrons in the wire to withdraw from the magnet due to the removal of electrical force. Similarly, the operation of the electric current through the curled conductor creates a magnetic field, the direction of which is opposite the current due to electric inertia.
The two main electricity measurements are controlled by most of the behavior that electricity shows when interacting with objects: voltage and resistance from which measurement measurement for the current comes. The voltage is the amount of electrical potential that exists from one point to another, similar to the pressure created inside the activated water hose. The higher the voltage between two points, the greater the electrical will flowthe pressure and the current. The concept of resistance describes the inclination of the object to resist electric flow. Electric current in the amps that flow from one point to another can be expressed as a voltage divided by resistance in the ohms.
Electric current is either an alternating current or a direct current. The difference is the direction of the flow; AC current switches instructions tens per second with inverted polarity. The direct current maintains polarity and therefore flows in only one direction, for example through a battery.
