Cuando se instalan varios receptores, éstos pueden ser montados de diferentes maneras:
- En serie
- En paralelo
- Mixtos
En un circuito en serie los receptores están instalados uno a continuación de otro en la línea eléctrica, de tal forma que la corriente que atraviesa el primero de ellos será la misma que la que atraviesa el último. Para instalar un nuevo elemento en serie en un circuito tendremos que cortar el cable y cada uno de los terminales generados conectarlos al receptor.
En un circuito en paralelo cada receptor conectado a la fuente de alimentación lo está de forma independiente al resto; cada uno tiene su propia línea, aunque haya parte de esa línea que sea común a todos. Para conectar un nuevo receptor en paralelo, añadiremos una nueva línea conectada a los terminales de las líneas que ya hay en el circuito.
Caída de tensión en un receptor
Aparece un concepto nuevo ligado a la tensión. Cuando tenemos más de un receptor conectado en serie en un circuito, si medimos los voltios en los extremos de cada uno de los receptores podemos ver que la medida no es la misma si aquellos tienen resistencias diferentes. La medida de los voltios en los extremos de cada receptor la llamamos caída de tensión.
La corriente en los circuitos serie y paralelo
Una manera muy rápida de distinguir un circuito en seria de otro en paralelo consiste en imaginala circulación de los electrones a través de uno de los receptores: si para regresen a la pila atravesando el receptor, los electrones tienen que atravesar otro receptor, el circuito está en serie; si los electrones llegan atravesando sólo el receptor seleccionado, el circuito está en paralelo.
series and parallel circuit
So far we have considered circuits with a single receiver, but the truth is that it is common to find multiple receivers on the same circuit.
When installing several receptors, they can be assembled in different ways:
serially
in parallel
mixed
Series circuits
In a series circuit receivers are installed one after another in the power line, so that the current through the first of them is the same as that passing through the latter. To install a new element in series in a circuit which will cut the cable and each of the terminals connect to the receiver generated.
Parallel circuit
In a parallel circuit each receiver connected to the power supply it is independently of the other, each has its own line, even if part of that line that is common to all. To attach a new receiver in parallel, add a new line connected to the terminals of the lines already in the circuit.
A voltage drop in receiver
A new concept appears linked to stress. When we have more than one receiver connected in series in a circuit, if we measure the volts at the ends of each of the receivers can see that is not the same as if those are different resistances. The measurement of volts at the ends of each call receiver the voltage drop.
The current in series and parallel circuits
A quick way to distinguish one from another serious circuit in parallel imagine it is movement of electrons through a receptor: whether to return to the stack through the receiver, the electrons must pass through another receiver, the circuit is in series, if the electrons reach the receiver through only selected, the circuit is in parallel.
