Why is that the outlets in our houses are wired in parallel, and never in series

In a ring circuit the cable goes from consumer board, to one outlet, then another, then another.........
What's the problem if you wired it in series, if the fuse for that oulet goes, then the devices that are plugged in that oulet will not word, but isn't that the same case for wiring it in a parallel?

Depends on how deeply you look at the wiring.

Treating the consumer board[fuse box] and outlet circuit, as being "boxed" circuit components the fuse and outlet circuit are in series- that's why when a fuse goes in consumer unit, all on a particular circuit is cut off. ie the fuse is in series with all on a particular circuit.

But if you look "inside" the conceptual black box that is the outlet circuit, you find each outlet is parallel wired with other outlets within that circuit still means the fuse is in series with all that circuits components, but those components within a particular circuit are in parallel with each other.

This could this be question involving ring wiring topology?
In a ring circuit the cable goes from consumer board, to one outlet, then another, then another.... and then joins back up with the consumer board. At first glance that might look like series too , but looking inside the sockets on the ring circuit, you'll find the rather than splitting the cable through the output, each outlet contains an electrical T for each of live, neutral, and earth on the ring.There's always a path for current to flow around the ring, regardless of whether there's a plug in the socket.

point to point wiring[think it's largely obsolete except for specialised/heavy loads] , routes a single cable from consumer board to each outlet. Each cable is still electrically in parallel to any other outlet/cables on a particular circuit, but the additional bridging connections to produce any parallel circuitry is in/near the consumer board. Big disadvantage is it requires more length of cable, and the cores (wires within the cable) need to take the full load an outlet can take. With a ring, each wire is effectively doubled. Rings are also far better at distributing the stress placed on the cabling- if one side of a ring heats up due to heavy load, more of the current will be draw from the other side of the ring- tending to equalise heating within the cables.


Hope that helps some.

Rather seems to me that some review of series and parallel wiring is in order. Wiring receptacle in series would guarantee that none would work unless a load was plugged in.

If 'it was wired in series' then there's be NO voltage unless
something was plugged in and operating at every outlet right?
The voltage would vary, outlet to outlet, with diffeent loads connected right?
How would that work out for ya?
