今天重庆新航道的小编要给大家分享的是IGCSE物理电学模块真题的练习讲解,看了这些题目,小编觉得对于我们中国学生来说还是有优势的,基本上是我们在正常学习过程中老师给我们讲授的内容,所以大家适应英文题干就好啦。下面就是IGCSE物理真题的分享,大家有需要就拿去吧。
1. Which statement is correct?
A A fuse is included in a circuit to prevent the current becoming too high.
B A fuse should be connected to the neutral wire in a plug.
C An electric circuit will only work if it includes a fuse.
D An earth wire is needed to prevent the fuse blowing.
2. The diagram shows a torch containing two 2 V cells, a switch and a lamp.
What is the circuit diagram for the torch?
3. The circuit shown contains four lamps and three switches.
Which switches must be closed to light only lamps 1 and 3?
A switch 1 only
B switch 1 and switch 2 only
C switch 1 and switch 3 only
D switch 2 and switch 3 only
4 Which circuit shows how a voltmeter is connected to measure the potential difference across the cell?
5. When the thermistor in the circuit below is heated, the lamp becomes brighter.
Why does this happen?
A The resistance of the lamp decreases.
B The resistance of the lamp increases.
C The resistance of the thermistor decreases.
