All connections are made in parallel. e.g. lights, fans, socket outlets all are arranged in parallel. However the control switch of any device like a fan or light is put in parallel to that.
the wiring starts by dividing the main connection to a number of points same as the number of rooms in ur residence. Each goes through a Circuit breaker, and then to the room where the line is further divided depending on the number of appliances, sockets, power plugs. Each line then goes to the respective point then connects to the load and at the other side of the load is the neutral which is common through the residence.
