Answer:
Explanation:
better way to connect lights and other electrical appliances in domestic wiring is Parallel Circuit
Because parallel circuit will allow independent use of light & appliances.
Christmas tree lamps are usually wired in series. if one lamp breaks then Whole Christmas tree stop working
An electrician has wired a house in such a way that if a lamp gets fused in one room of the house, all the lamps in other rooms of the house stop working
=> Electrician has used series wiring instead of Parallel Wiring
