电流和电路单元测试卷(解析版)
电流和电路单元测试卷（解析版） 一、初三物理电流和电路易错压轴题（难） 1．在探究“并联电路各支路中的电流与干路电流的关系”时，小明同学在实验室选取：电流表3只，灯泡2只，开关1个，干电池，导线若干． （1）请你帮助小明设计一个能够同时测量出支路和干路电流的电路，把你设计的实验电路图画在方框内． （______） （2）小明同学按照电路图连接实物，把最后一根导线连接完毕后，看到灯泡立即发光，一个电流表指针向零刻度的左边偏转．小亮认为在实验操作中有两处错误，其中一处是 _____，还有一处是_____． （3）小明排除故障后开始实验，正确得出电流表示数如表 实验次数I1/A I2/A I3/A 1 0.100.20 0.30 分析表格中的数据，小明发现并联电路干路中的电流和支路中的电流关系是_____（可用字母表达式表示）．但为了使实验结论更具科学性，请你提出一条合理化建议：_____． 【答案】连接电路的过程中，开关没有断开电流表的接线柱接 反了 I3=I1+I2更换不同的灯泡进行多次实验 【解析】 【分析】 （1）连接电路时，开关应断开；（2）电流表串联在电路中，电流要正进负出；（3）多次实验找出普遍性规律； 【详解】 (1)从电源正极依次串联开关、灯泡L1、电流表A1、电流表A回到电源负极，然后将灯泡L2和电流表A2串联后并联在灯泡L1和电流表A1两端，如下图所示：
(2)把最后一根导线连接完毕后，看到灯泡立即发光，说明连接电路的过程中，开关没有断开；一个电流表指针向零刻度的左边偏转，说明电流表的接线柱接反了． （3）由表中数据分析可以知道，并联电路中干路电流等于各支路电流之和，即I3=I1+I2 一组实验数据具有偶然性，要得到普遍规律，需多次实验得到多组实验数据，因此需更换不同的灯泡进行多次实验． 2．如图是一个模拟交通路口红绿灯工作的实验电路，请你用笔画线代替导线，只添加两根导线，实物电路图补充完整．要求：红灯亮时，黄灯和绿灯都不亮；当红灯灭时，黄灯和绿灯可以分别亮一盏． 【答案】 【解析】 由题意知红灯亮时，黄灯和绿灯都不亮；当红灯灭时，黄灯和绿灯可以分别亮一盏．说明三盏灯互不影响，也就是说三盏灯是并联；结合实物图，S1是控制红灯和黄灯；S2控制绿灯和黄灯，故连接电路图如图． 3．（一）用下图所示的装置探究摩擦力跟接触面粗糙程度的关系。 （1）实验时，用弹簧测力计水平拉动木块，使它沿长木板做运动，根据知识，从而测出木块与长木板之间的滑动摩擦力。

九年级物理电流和电路单元测试卷(解析版)
九年级物理电流和电路单元测试卷（解析版） 一、初三物理电流和电路易错压轴题（难） 1．某小组同学通过自学得知：在两种金属组成的回路中，如果使两个接触点的温度不同，便在回路中将会出现电流．为了验证和探究其中规律，该小组利用铁丝和铜丝两种导线组成图（a）所示的闭合回路，并将相连的两个交叉点A、B分别置于烧杯中和酒精灯上方．做了如图（a）、（b）、（c）、（d）所示的四次实验．请仔细观察图中的装置、操作和现象，归纳得出初步结论． （1）分析比较图中（a）（b）两图中的装置、操作和现象，归纳得出初步结论：当相互连接的两种金属丝的材料不变时，接触点之间的温度差越小，电路中的电流________．（2）分析比较图中（a）（c）两图[或（b）（d）两图]，发现当相互连接的两种金属丝的材料相同，金属导线接触点之间的温度差也相同，且用酒精灯对金属导线中部进行加热时，闭合回路中的电流表示数________（选填“变大”、“不变”或“变小”）．据此可得出初步结论：当相互连接的两种金属丝的材料相同，金属导线接触点之间的温度差也相同时，电路中的电流大小与金属导体中部温度高低________． 【答案】越小不变无关 【解析】 【分析】 【详解】 (1)比较a、b两次实验可知,当相互连接的两种金属丝的材料不变时,(a)中冰水混合物与酒精灯火焰的温度差比较大,电流表示数大;(b)中开水与酒精灯火焰的温度差较小，电流表的示数小，故可得出的结论为：当相互连接的两种金属丝的材料不变时，接触点之间的温度差越小，电路中的电流越小；(2)分析比较图中(a)(c)两图(或(b)(d)两图)，发现当相互连接的两种金属丝的材料相同，金属导线接触点之间的温度差也相同，且用酒精灯对金属导线中部和最长处进行加热时，闭合回路中的电流表示数相同，据此可得出初步结论：当相互连接的两种金属丝的材料相同，金属导线接触点之间的温度差也相同时，电路中的电流大小与金属导体中部温度高低无关． 【点睛】 根据图示判断两个接触点的温度差，然后比较实验中电流表的示数，并与已有的结论对比． 2．在“用伏安法测电阻”的实验中： （1）实验原理是_______________________。
系统测试与集成测试区别
系统测试和集成测试的区别 一般的小系统区分不是很大的。 1、计划和用例编制的先后顺序 从V模型来讲，在需求阶段就要制定系统测试计划和用例，HLD的时候做集成测试计划和用例，有些公司的具体实践不一样，但是顺序肯定是先做系统测试计划用例，再做集成。 2、用例的粒度 系统测试用例相对很接近用户接受测试用例。 集成测试用例比系统测试用例更详细，而且对于接口部分要重点写，毕竟要集成各个模块或者子系统。 3、执行测试的顺序 先执行集成测试，待集成测试出的问题修复之后，（配置管理，基线化），再做系统测试。 4、用例的数量 系统测试的用例数量一般比集成测试的用例数量少，具体的数量要根据各个公司的性能基线来确定，一般写不到这个数量的测试用例还通不过审计。 系统测试这个称呼往往被用于压力测试、容量测试、性能测试、安全测试等方面。 而集成测试这个称呼往往被用于细节化的功能测试的超集——从用户需求来设计和组织较大颗粒度的功能测试。 系统测试最主要的就是功能测试，测试软件《需求规格说明书》中提到的功能是否有遗漏，是否正确的实现。做系统测试要严格按照《需求规格说明书》，以它为标准。测试方法一般都使用黑盒测试 法； 集成测试在系统测试之前，单元测试完成之后系统集成的时候进行测试。集成测试主要是针对程序内部结构进行测试，特别是对程序之间的接口进行测试。集成测试对测试人员的编写脚本能力要求比 较高。测试方法一般选用黑盒测试和白盒测试相结合。 集成测试：是在软件系统集成过程中所进行的测试，其主要目的是检查软件单位之间的借口是否正确。它根据集成测试计划，一边将模块或其他年间单位组
合成越来越大的系统，一边运行该系统，以 分析所组成的系统是否正确，各个组成部分是否合拍。集成测试的策略主要有自顶向下和自底向上两种。也可以理解为在软件设计单元、功能模块组装、集成为系统时，对应用系统的各个部件（软件单元 、功能模块接口、链接等）进行的联合测试，以决定他们能否在一起共同工作，部件可以是代码块、独立的应用、网络上的客户端或服务器端程序。 系统测试：系统测试是基于软件需求说明书的黑盒测试，是对已经集成好的软件系统进行彻底的测试，以验证软件系统的正确性和性能等满足其规约所指定的要求，检查软件的行为和输出是否正确， 并非一项简单的任务，被称为测试的“先知者问题”。因此，系统测试应该按照测试计划进行，其输入、输出和其他的动态运行行为应该与软件规约进行对比。软件系统测试的方法很多，主要有功能测试 ，性能测试，随机测试等。 通俗的讲，一个产品从研发到出厂的工程中，测试分为三个阶段：单元测试、集成测试、系统测试；单元测试：一个模块的功能及常规错误测试；集成测试：完成单元测试后，各模块联调测试；集 中在各模块的接口是否一致、各模块间的数据流和控制硫是否按照设计实现其功能、以及结果的正确性验证等等；可以使整个产品的集成测试，也可以使大模块的集成测试；系统测试：针对整个产品的 全面测试，既包含各模块的验证性测试（验证前两个阶段测试的正确性）和功能性（产品提交个用户的功能）测试，又包括对整个产品的健壮性、安全性、可维护性及各种性能参数的测试。
