(a) Which is the better way to connect lights and other electrical appliances in domestic wiring: series circuits or parallel circuits? Why?

(b) Christmas tree lamps are usually wired in series. What happens if one lamp breaks?

(c) 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. What is the defect in the wiring?

(d) Draw a circuit diagram showing two electric lamps connected in parallel together with a cell and a switch that works both lamps. Mark an Ⓐ on your diagram to show where an ammeter should be placed to measure the current.
