So that if a fuse in one building fails the others will still have a viable supply. If they were wired in series then one fuse blowing would stop the entire circuit and every building would lose power.
A parallel circuit
Switches used in electrical circuits are wired in series with either a parallel or series load. In parallel loads, the switch is upstream from the parallel circuit, so that the switch will shut off all of the parallel circuits.
Normally I would expect the elements to be wired in parallel so that the loss of one element does not cause the others not to work. It is possible for some manufacturers to wire a pair of elements in series so that they could use say 110v elements as standard so that they can be utilized on 230v toasters as well.
Normally putting the batteries in series would have more effect.
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
yes
Electrical wiring for buildings is always done in parallel circuits.
They are wired in parallel, series and series - parallel.
So you don't have to turn on all the lights at the same time.
In parallel.
Parallel
Always parallel. Homes should never be wired in series. (That would be like the old Christmas tree lights where, if one bulb burned out, the entire string would not light up.)
Parallel. Simple.
Electrical outlets are wired in parallel.
there is no country that does not have parallel lines on their buildings. this is proven.
paralell
Any number of fresh D cells wired in parallel will yield a voltage of 1.5 volts.
