How the current?
How the current?. Current work using three kinds of forces:
1 volt - voltage -
3 ome - electrical / ohmic resistance - These three forces operate as a unit within a given circuit to allow the free flow of electricity from one place to another.
Electricity and power transmission process begins when the electrons of an atom move and begin to move and create what we call electricity. Different objects can be better or worse conductors current depending on the activity of atoms. If the atom is firmly holds its electrons - which means that electrons are really close to the nucleus and the nucleus - then this atom will carry a good flow of electricity as an atom holds its electrons away from the core. This is why some materials - metals like salt as silver, gold and aluminum - are good conductors of electricity. They are made of these types of atoms that hold the electrons away from the core. When we talk about the materials that are not good conductors of electricity, we think of glass, plastic, and even and air. These things and concepts are called insulators, a composition of their atoms prevents the flow of electricity. Electrical voltage and current circuits
Now that we understand how electricity works at the molecular level, lets look at the physical process of creating electricity. electrons though small, requires a kind of power that will run them, just as the need to push the stone to skotrljao down the hill. force that drives electrons into electricity is called electromotive force or EMS. term for which you may have heard that describes the EMS is an electric voltage. Electric power is transmitted through the circuit. exchange of electric power is supplied to a power source, something called a filling, and at least two wires that carry electricity between the power source and electric charge. Imagine that our source of electric batteries and electric charge of the bulb screwed in stonoj lamps. All power sources have positive and negative terminals. negative terminal of the circuit that is used to push electrons through a circuit. wire which starts from the negative terminal is connected the filling - in our example, a light bulb - and further on the wire connecting the positive pujenje Cooley clamp connected to the source. amount of force applied by the power source is what determines the amount of electric charges passing through a circuit. word amp refers to the amount electrons moving through the circuit. Amperage is a measure of electrical current. Resistance
last aspect of electricity that needs to understand is called resistance. Imagine water flowing through the pipe. The greater the tube to the water easier to move through it. Flowing million liters of water through a garden hose would take much longer than the display of the same quantity of water through the channel. When electricity came to the part of the circuit called a charge - as is our light bulbs -, worry of Charging takes the same amount of electricity. When electric light bulbs, small bulbs inside the fiber wire becomes charged as much electricity as the wire that carries electricity. When electric current flows through the fiber in the bulb, the electrons of the atom currents become very crowded as it is moving through a small space - as water that accumulates behind the dam. Just as a small area reservoir dam holds water, a small area within the fibers greatly increases the electron energy. This accumulation of energy is what makes the bulb light up. And lo! This creates a current.
Power operates using three kinds of forces:
