pte阅读要寻文章的主旨,任何一篇文章的写作都是有主旨的,即便在我们不是非常熟悉的pte考试中,pte阅读部分中会出现pte词汇较为陌生,让我们对于理解pte阅读部分由一定的难度,但是我们寻找到文章的主旨,就会在pte考试中取得优异成绩。今天小编为大家带来pte单词ammeter的注解。
UK: ['æmi:tə(r)]
US: ['æmi:tə(r)]
复数:ammeters
n.
1.电流表,安培计
2.安培表
3.电流计
4.〔物〕安培计
1 . An instrument used to measure the flow of current in a circuit is called an ammeter.
用来测量电路中电流流量的仪器叫做电流表。
2 . Since the voltage drop across the ammeter is negligible, essentially all the test voltage appears across R.
由于安培计上的电压降可以忽略,所以所有的测试电压都出现在电阻R上。
3 . If the component or material breaks down, all the voltage would be applied to the ammeter's input, possibly destroying it.
如果元件或材料发生击穿,全部电压都会加到安培计的输入端,从而可能将其损坏。
4 . To start with, you need to break the circuit so that the ammeter can be connected in series.
开始时,你需要断开电路,以让电流表可以串入。
5 . The guard can be used to isolate the high impedance input lead of the ammeter from leakage current due to voltage sources.
保护可以用来把安培计的高阻输入引线和由电压源引起的泄漏电流隔离开来。
PTE考生们在PTE备考时,一定要多看做一些PTE阅读基础练习题,祝大家能够取得好成绩。
