1、大学 专业英语 科技英语作文中英对照Electronic circuit By the metal wires , the electrical and the electronic components of conductive circuits, called electric circuit. The circuit which is ran through by Dc called dc road, The circuit which is ran through by alternating current called ac circuit. The most simple ci
2、rcuit, is made up by the power supply, the load, the wire and the switch components. Circuit conduction called pathways. Only the circuit is pathways, the electric current can run through the circuit. The circuit is broken called open circuit. A part of the circuit that the ends are connected direct
3、ly ,make the voltage of this part is zero, called a short-circuit. Open circuit is allowed, but short-circuit is never allowed, because a short circuit will lead to that the power, the appliances and the ammeter is burnt out. In the series circuits, the switch control the whole circuit in any positi
4、on. The current have only one way can through the circuit, the current which run through one lamp must through another lamp. If a lamp is crushed out, another lamp must be crushed out. The advantages of the serises circuits is that if you want to control all the circuits,you can use the series circu
5、its. But as long as there is a particular disconnected, the circuit will become the open circuit. The components of this circuit can not work normally. Parallel connection circuit is made in the formation of the circuit components between parallel current has a more independent pathways, for circuit
6、 composed of two basic one way. The characteristic is the appliances between each other is not affected. A branch of appliances damaged ,the other branch was not affected. lectric circuit 由金属导线和电气以及电子部件组成的导电回路，称其为电路。直流电通过的电路称为“直流电路”;交流电通过的电路称为“交流电路”。最简单的电路，是由电源、负载、导线、开关等元器件组成。电路导通叫做通路。只有通路，电路中才有电流通过
7、。电路某一处断开叫做断路或者开路。电路某一部分的两端直接接通，使这部分的电压变成零，叫做短路。开路是允许的，而短路决不允许，因为短路会导致电源,用电器,电流表被烧坏。 是由自然界产生周期性变化的连续性的物理自然变量，在将连续性物理自然变量转换为连续的电信号，并通过运算连续性电信号的电路即称为模拟电路。 将连续性的电讯号，转换为不连续性定量的电信号，并运算不连续性定量电信号的电路，称为数字电路。 串联电路中开关在任何位置控制整个电路。电流只有一条通路，经过一盏灯的电流一定经过另一盏灯。如果熄灭一盏灯，另一盏灯一定熄灭。优点：在一个电路中， 若想控制所有电路， 即可使用串联的电路；缺点：只要有某一处断开，整个电路就成为断路。 即所相串联的电子元件不能正常工作。 并联电路是使在构成并联的电路元件间电流有一条以上的相互独立通路，为电路组成二种基本的方式之一。特点：用电器之间互不影响。一条支路上的用电器损坏，其他支路不受影响。
