The first diagram shows a simple electrical circuit: two cells, a switch, a bulb, and two meters. The scale diagram shows the reading on the ammeter when the switch is closed.

1. aDescribe the circuit diagram that represents the circuit (draw it on paper). [3]
2. bRecord the ammeter reading, I. [1]
3. cCalculate the resistance of the bulb, using IR = 3, where I is the ammeter reading and R is the resistance. [2]

You'll mark your own answer against the marking guide when you hand it in.
