Why parallel circuits are used for house lights?

Answer 1

bcz when we connect the circuit in series then- -the voltage divides, therefore all the appliances do not wrk properly -in series if one appliance is switched off then all the other appliances also gets switched off i.e.u should have diff. switch off n on key.. this is d reason y we prefer parallel connection so that if 1 appliance doesn't wrk properly then all the connections do not get affectd

Answer 2

That's a very interesting matter to think about. If all of the wiring in your house

were arranged in a single big series loop, then here's how the house would

operate:

-- Every single electrical device in the house would have to be either on or off

at the same time. If any one device were switched off, unplugged, or burned

out, then none of the others could operate, because there would be a gap in

the series loop.

-- The 117-volt supply from the utility pole to the house would be divided

among all the devices in the loop. The way the math works out, that means

that the devices designed to use the most power ... like the air conditioner,

the electric stove, and the brightest lights ... would receive the least power.

-- And when you replaced one light bulb with another one designed for

a different power level, the power consumed by every other device in

the house would change !

Not a very convenient configuration.

A parallel configuration allows each device to operate independently,

unaffected by any others in the house.

Also, if you arrange in parallel, the light will be brighter rather than when you arrange in series.

If everything in your house were wired in series instead of parallel, then:

-- You would need to keep everything on all the time. That includes the microwave,

the toaster, all the stove burners, all the lights in the house, etc. If any one device

were switched off, unplugged, or burned out, none of the others would work.

-- The 117 volts supplied by the electric company would divide up among all the

electrical devices in the house.

-- The appliances requiring the most power ... the stove, toaster, water heater,

hair dryer ... would get the smallest share of the voltage, and would have access

to the least power.

-- The devices designed to use the least power ... the clock radio, cellphone charger,

night-light ... would get the greatest share of the voltage, and would have access to

the most power.

-- If a device failed ... like a burned out light bulb ... everything in the house would

go dark. You'd have a tough time determining which one failed.

-- Every time you changed a device ... like replacing a light bulb with another one of

a different size, or getting a stronger microwave ... the whole distribution of voltage

and power to every device in the house would change.

Not a very convenient arrangement. As soon as the first pioneer began to wire

his house on the prairie, it was pretty obvious that the parallel configuration

was the way to go.
