ELEMENTARY ELECTRIC CIRCUIT PARAMETER.
electrical potential difference (ddp). Electric voltage.
The potential difference or voltage is the cause that allows the movement electric current from one point to another electrical circuit. If there is no potential difference can not be established electrical current flow.
transpariencia The following is the hydraulic metaphor of representing the potential difference in the electrical circuit.
When entering deposits, A and B, there is no difference in level, the energy potential of both deposits is the same and therefore can not be established movement of water between them. When deposits
between A and B, there nivle difference, potential energy is different, the tank A has more potential energy than B and therefore if you can provide water circulation between the two deposits.
Therefore we can define:
electric voltage or potential difference. (V)
is the power level difference between any two points in the electrical circuit (similar to the difference of level in the hydraulic circuit.)
his unit is volt (V)
Amperage electric.
resulting effect is the property that all bodies are electrically neutralized.
The intensity of electric current a priori be related the degree of potential difference existing in the electrical circuit.
If we think of the above simile is clear that, other things being equal, the intensity of water flow (expenditure) will be directly proportional to the difference in level between the two reservoirs.
Therefore we can define.
intensity electric current (I)
intensity is the speed at which the electron beams moving the wire. (The water flow in hydraulic circuit)
Its unit is the ampere (A).
electrical resistance.
electrical resistance is the opposition that drivers oppose the flow of electric current. It is characteristic of each substance.
The elementary electric circuit manisfiestan two types of resistance:
- The opposite conductors for electrical circuit.
- opposed by the load circuit. (Eg lamp)
is represented by the letter R, and its unit, the ohm (Ω).
Referring back to hydraulic analogy:
- Why driving style more easily circulate the water?:
a) For a totally smooth copper.
b) For a concrete with many ridges.
Obviously circulate more easily by driving copper if other factors remain constant driving (section, length, etc.).
- When the higher the "cost" of water?
a) When the gap between A and B deposits as large as possible.
b) When the gap between A and B deposits as small as possible to establish the flow of water.
seems logical that in the situation) water circulation will be faster and therefore a greater potential difference favors the flow of current if the other variables are held constant circuit.
