Question

Look carefully at these two circuit diagrams and answer the questions that follow.
figure

(a) How many cells are there in each diagram?
(b) Which of the circuits, i and ii, is a parallel circuit?
(c) In circuit i, if bulb A fuses, what will happen?
(d) In circuit ii, how could you get only bulb D to light?

Answer 1

(a) There are four cells in each diagram.

(b) Circuit (ii) is a parallel circuit.

(c) The bulbs in circuit (i) are connected in series; therefore, if bulb A fuses, both the bulbs will not light up.

(d) In circuit (ii), if bulb D is switched ON, only bulb D will light up.
