Diagram 1 Diagram 2 1.What components do the letters A, B and C represent?

A Wires B Battery C..Lights.

2.What is the name given to the way the bulbs are arranged in Diagram 1?

Series circuit

3.What is the name given to the way the bulbs are arranged in Diagram 2?

Parallel circuit
4.In a series circuit, like in Diagram 1, how is the brightness of the first bulb affected when the second bulb is connected? Explain why this happens?





5.In a parallel circuit, like in Diagram 2, how is the brightness of the first bulb affected when the second bulb is connected? Explain why this happens?



6.Give one example of where we might find a series circuit in everyday life.



7.Give one example of where we might find a parallel circuit in everyday life.



8.Explain one advantage of using a parallel circuit rather than a series circuit.



9.Dan and Tom build a circuit like the one shown below.

(a)Name the component labelled X

(b)What are Dan and Tom using the component labelled X to measure?

(c)Dan says, “Ammeter 1 will show a lower reading than Ammeter 2 because the bulbs in the circuit use up the current.”
Tom says, “Ammeter 1 will show the same reading as Ammeter 2 because current is not used up.”
Who is right?

(d)If Ammeter 1 has a reading of 1.5A, what reading will Ammeter 2 show? A

10. (a) The circuit above contains 2 cells. Describe what would happen to the bulbs if Dan and Tom added another cell.



(b) Describe how the reading on the reading on the ammeters would change if another cell was added to the circuit.
