工业电工技术主要包括电气设备的设计生产和维修技术，工业电气设备门类众多，涉及到全部工业领域。
所以工业控制领域的电工技术就分得比较细了，有化工 纺织 塑料 石油 机械等等工业类型，他们对电工技术的要求都不一样。但是也都有很多通用部分。
后来，电工技术不断发展，人们发明了半导体，慢慢的形成了一个新的电学技术门类，那就是接下来要讲的电子技术
鉴于电子技术突飞猛进，给人类发展带来的巨大影响，现在都是独立成一个技术系统了
电子技术的进步极大的促进了信息技术的发展，呈现出前所未有的迭代更新速度！
电子技术的迅猛发展，让全世界人们的生活发生了翻天覆地的变化：
从通信靠吼到有线电话，从有线电话到无绳电话，从无绳电话到2G手机，再到3G4G手机，如今人人都是4G5G智能手机，不远的将来会是6G手机。。。。。。
从传统珠算盘到计算器，计算器到COM计算机，从COM机到WINDOS95系统，从WINDONG2000到今天的WIN10，再到国产华为的鸿蒙。以及大型超级计算机系列，中国超级计算机算力已经达到千万亿次。。。。。。。
从面对面的购物到网上下单，从现金交付到电脑网络支付，从网络支付到手机支付。。。。。

电路是电流的通路，它是为了某种需要由某些电工设备或元器件按一定方式组合起来。
5、电工电子技术论文3000字A circuit is a path of current that is combined in a certain way by certain electrical equipment or components for some kind of need.
The two major functions of the circuit: to achieve the transportation and conversion of electrical energy; Transmit and process signals
电力系统：可通过变压器和输电线两部分中间环节运输到负载实现电能的运输和转换。
6、电工电子技术期末考试试题及答案Power system: The transportation and conversion of electrical energy can be realized by transporting it to the load through the intermediate links of transformers and transmission lines.
扩音器：由信号源输出电信号（电压、电流）再通过放大器把信号传递和处理（调谐、变频、检波、放大）送到负载。
Amplifier: The output electrical signal (voltage, current) from the signal source and then transmits and processes the signal (tuning, frequency conversion, detection, amplification) to the load through the amplifier.
7、电工电子技术基础知识点Circuit model: there are mainly resistive components, inductive components, capacitive components, power supply devices.
Reference direction: You can arbitrarily select a certain direction as the reference direction of the current (positive direction)
实际方向：当电流的实际方向与参考方向一致时，电流为正。当电流的实际方向与参考方相反时，电流为负。
8、电工电子技术平时作业1答案Actual direction: When the actual direction of the current is consistent with the reference direction, the current is positive. When the actual direction of the current is opposite to the reference party, the current is negative.
Voltage direction: The high potential end points to the low potential end
Electromotive force direction: The low potential end points to the high potential end
9、电工电子技术单元自测题答案欧姆定律：R=U/I，R为线性电阻，表示该电路特性与电流和电压无关
Ohm's law: R=U / I, R is a linear resistance, indicating that the circuit characteristics are independent of current and voltage
On-load operation: Power and load
10、电工电子技术论文3000字Power supply: U and I actually go in opposite directions, flowing out of the "+", emitting power;
Load: U and I are actually in the same direction, flowing in from "+", taking power
Ro为电源内阻,当Ro越小，电流越大，电源端电压下降越多，负载电压越接近电动势。
