Why are houses wired with parallel circuits?

Answer 1

voltage drop across all the parallel elements is equal and it is equal to input voltage.

we know for home applications in voltage and frequency is fixed, ex: in India voltage=230v and frequency=50 Hz. All devices we used in home having voltage specification =230 to 240v, but different current. so home use parallel circuits.

To make this a bit more general, in a series circuit each device in the circuit has some dependence on all the other items. A simple example is a number of light bulbs in series. If any one light bulb burns out the circuit opens and all the other bulbs go out. Also if you needed to add more bulbs in the same series circuit then all bulbs would be dimmer.

Answer 2

Because the supply voltage is common to each branch of a parallel circuit, each appliance receives its rated voltage which is necessary for the appliance to operate at its rated power. This is the main reason. Another reason is, should one appliance fail, then -unlike a series circuit- the other appliances will keep working.

Answer 3

A circuit connected in series makes current to flow in a single path. Any break on the circuit will cut the flow of current. As such, home appliances are connected in parallel to ensure switching one of them off does not affect others.

Answer 4

Any electrical device will only operate at its rated power provided it is supplied with its rated voltage. Rated power and rated voltage are both shown on a device's nameplate data label. The only way to ensure that all the appliances, lamps, etc., in a home are supplied with their rated voltage (i.e. the supply voltage) is to connect them in parallel -because each branch of a parallel circuit shares a common voltage.

Answer 5

Because if they were in series instead, then . . .

-- you'd have to turn everything on at once in order for anything to work;

-- if any single electric thing turned off or burned out, then everything would

turn off, and you would have no way of knowing which one was responsible;

-- the things that need the most power to run, like air conditioners and electric

stoves, would get the least amount of voltage, while the things that need the

least power, like night lights and clock radios, would get the most voltage;

-- every time you changed a light bulb and put in one of a different size, the

brightness of every light bulb in the house would change.

Answer 6

Because household appliances all run on mains voltage.
