CIE iGCSE Co-Ordinated Science P4.3.2 Series and parallel circuits Exam Style Questions Paper 1

Question 

Two lamps are connected in the circuit shown.

Which of these two statements about the circuit are correct?

1) There is a separate switch to control each lamp.

2) The ammeter measures the current in both lamps.

A) neither 1 nor 2

B) 1 only

C) 2 only

D) 1 and 2

▶️Answer/Explanation

Answer: B) 1 only

Explanation: In the circuit, each lamp has a separate switch, but the ammeter measures the total current in the circuit, not just the current in both lamps.

Question 

Three resistors are connected in series with a battery, as shown.

The current at point P is 6.0 A.

What is the current at point Q?

A 0 A

B 2.0 A

C 3.0 A

D 6.0 A

▶️Answer/Explanation

Answer: D 6.0 A

Explanation: In a series circuit, the current is the same at all points. Therefore, the current at point Q is the same as at point P, which is 6.0 A.

Question

The diagrams show a series circuit and a parallel circuit. One ammeter in the parallel circuit is

labelled P.

Which statement is correct?

A    The total resistance of the series circuit is 3.0 .

B    The total resistance of the parallel circuit is 6.0 .

C    In the series circuit, the readings on the ammeters are the same.

D    In the parallel circuit, the reading on ammeter P is less than the reading on either of the other

two ammeters
