You want every electrical device in the house to have equal access to the 117 volt utility supply at the
wall outlets. That means that every device in the house must be connected directly to the pair of wires
entering the house from the pole ... which is a pretty good definition of a "parallel" configuration.
Another reason, purely pragmatic, for not wiring household devices in series: Just like the old-fashioned
technique for constructing strings of Christmas-tree lights ... if household devices were connected in series,
then every device in the house would have to be switched ON, otherwise none of them would work !
If any single device were switched off, then there would be no current path through the series string.
And here's another little thing to consider: In a series string, each individual resistance in the string
has an influence on the current through the string. As a practical matter, that means that if everything
in the house were connected in series, then as the toaster heated up and its resistance increased, all the
lights in the house would dim, and the refrigerator would run a little slower. Definitely inconvenient.
So that each outlet, light, etc. can function independantly. If they were wired in series you'd have to turn on the light in the kitchen for the refrigerator outlet to work.
AnswerIt depends on how the builder and architect wanted it designed. It is also cheaper, easier to install, and more convenient to put them in vertically instead of horizontally.Answer
Parallel circuits have a constant voltage (ignoring conductor losses). A residence might have 3 or 4 or 5 or more 120 volt outlets wired this way in one room or in one area and on one circuit breaker. Has nothing to do with independent function or the wants of a builder.
Parallel connection in a circuit allows each device to switch on or off without cutting off the current. As such, household appliances need to be connected in parallel in order to operate independently.
It's important to configure the electric service in the home in parallel, because series wouldn't work.
Series wouldn't work because:
1). No current flows in a series circuit if the circuit is open anywhere. The practical implication
of this in the home is that if one light were turned off, nothing in the house would get any power.
2). In a series circuit, the largest resistance dissipates the largest power. The practical implication
of this in the home is that the night light and the electric clock would get the most power, while
the air conditioner, the stove, and the hot water heater would get the least power.
(1) To ensure that the voltage across each appliance is the same and equal to the supply voltage (otherwise none will operate at their rated power), and (2) to ensure that all the other appliances continue to work should one appliance fail.
All the household equipment are connected in parallel.
The reason is that in parallel connected components voltage remains same and in series connected components current remains the same.
The equipments used in household are of same voltage rating. see any equipment at home.
The wiring is done in such a way that equipments get connected in parallel and have same voltage across them.
one appliance blows off then the remaining will not work if connected in series
Because if they are connected in series then if one of them is turned off the rest will also shut off and also because in series connection the potential is distributed while for a typical household appliance the voltage should be the same.
it reduces the chances of short circuit and overloading.
No change in supply voltage as additional resistance is connected in parallel circuit.
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
Components connected in series are connected along a single path, so the same current flows through all of the components.Components connected in parallel are connected so the same voltage is applied to each component
In parallel connection all the positive terminals are connected with positive of the source and all the negative terminals are connected to negative of the source. Whereas in series connection one positive terminal is connected to the negative of another, like wise it goes on and finally the positive end is connected to the negative of the source.
A voltmeter should be connected in a parallel connection
All home appliances are connected in parallel.
Because it one of the household appliances were to "go out" then all the household appliances would "go out" as well.
1) That way, all appliances have the same voltage, which doesn't depend on the number or the characteristics of other connected appliances. This is important for the correct operation of the appliances. 2) That way, switching off one appliance won't disconnect other appliances.
When things are connected in parallel, they all get the same mains voltage. When you connect things in series the voltage they get depends on the number of units in the series. Household appliances all need mains voltage so all electrics deliver this. (Apart from connecting up batteries, nearly all electrics are set up in parallel mode).
1) That way, all appliances have the same voltage, which doesn't depend on the number or the characteristics of other connected appliances. This is important for the correct operation of the appliances. 2) That way, switching off one appliance won't disconnect other appliances.
The can be connected in parallel, in series, or in some combination. Household appliances are connected in parallel, because that way:1. Each appliance receives the full voltage. Results are thus more predictable. For example, a light bulb will give the same light, no matter whether it is the only light bulb, or whether others are also connected.2. Each appliance will continue working even if the others are switched off.
Appliances have to be connected in a parallel circuit to keep the voltages the same for each appliance (they were designed to work with one voltage) , this does not mean that the power output will be the same, the more appliances there are the more current (i.e. power) will be needed to for the appliances and this can go on until the grid cannot supply any more (and you blow a fuse)
Dependable voltage; and you don't need to have all devices on or off simultaneously.
In a normal household configuration, the appliances are connected in parallel. This allows each of them to draw the amount of current they were designed to operate on. Unless you wired your own extension cord, you cannot connect them in series. Theoretically speaking (I hope you keep this theoretical), the loads in series increases the resistance of the circuit, which decreases the current through the circuit. None of the appliances would work properly. The more you connected, the less functional they become. There may be some other safety issues with their design compromised, but the appliances would not function properly and it is not possible to answer the question without some information about the appliances and power specs for each. Then it can be translated into a mathematical question.
There should be a connection point on the appliance. This needs to be hardwired into an electric box, often with a disconnect or breaker. In some cases you can buy or make a power cord that plugs into a dedicated outlet with a mating connection appropriate to the voltage and amperage requirements of the appliance. If the service does not already exist, you may want to employ an electrician.
