Why do you prefer parallel circuit in domestic electric wiring?

Answer 1

If domestic electrical wiring were one big series loop in a house, instead of

one big parallel network, then ...

-- Every outlet in the house would need something plugged into it and turned on.

If any one device in the house were turned off or unplugged, every device in the

house would lose power.

-- That means that every light would have to stay on, the refrigerator, air conditioner,

and stove would have to run all the time, and every radio and TV would need to play

all the time.

-- If any one device in the house failed ... like a burned out light bulb ... every

device in the house would lose power, and there would be no easy way to tell

which one failed. You would have to go around the house replacing each device,

one at a time, before you found one that would restore power to everything in

the house when it was replaced.

-- The voltage from the meter is typically 117 volts AC in the US and Canada,

and all of the electrical devices in your house are designed to operate with

117 volts of AC. But if everything in the house were in series, then the 117 volts

would divide among all of them. Some would get more of it, some would get less

of it, but when you added up the voltage going to every device in the house, it

would all add up to 117 volts.

-- In a series arrangement, the devices that need the most power, like the

freezer, the air conditioner, and the electric stove, would get the least voltage,

and dissipate the least power. Those devices that need the least power, like

night-lights and electric clocks, would get the most voltage, dissipate the most

power, and either burn out or explode within seconds.

And that's why I personally prefer parallel wiring in my house if I can get it.
