老师会对课本中的主要教学内容整理到教案课件中,到写教案课件的时候了。将教案课件的工作计划制定好,才能够使以后的工作更有目标性!你们清楚有哪些教案课件范文呢?为满足您的需求,小编特地编辑了“《电压》教案”,欢迎阅读,希望您能够喜欢并分享!
《电压》教案
教学目标
1.知道电压的意义、符号、单位及常见电压值.
2.知道电压表的作用与符号,知道正确使用电压表的规则,能识别和选择电流表量程,会正确读数.
教学过程
一、电压
自主预习
阅读课本第55、56页,完成下列填空:
1.要让一段电路中有电流,它的两端就要有电压.电源的作用就是给用电器两端提供电压.
2.通常用字母U表示电压,它的单位是伏特,简称伏,符号是V;常用符号还有千伏和毫伏.
3.我国家庭电路的电压是220V,一节新的干电池的电压是1.5V.
小组讨论
取一个灯泡用导线跟一节电池连通,再把这个小灯泡跟两节串联电池连通.观察两次小灯泡的发光亮度有何不同?说明电路中电流的强弱与电源的什么量有关?
解:第2次灯泡更亮,说明不同的电源提供的电压不同,使电路中形成的电流大小也不相同.
教师点拨
1.电压使电路中形成电流,电源是提供电压的装置.
2.电路中获得持续电流的条件:
(1)电路中有电源(或电路两端有电压)
(2)电路是连通的.
3.不同的电源提供的电压不同,使电路中形成的电流大小也不相同.
跟踪练习
1.干电池是一种常用、方便的电源.下列关于干电池的说法正确的是(D)
A.有的干电池提供直流电,有的干电池提供交流电
B.常用的1号、2号、5号、7号干电池的电压随号数的增大而增大
C.干电池是把电能转化为化学能的装置
D.多数干电池中有汞、镉等重金属元素,随便丢弃会污染环境.所以,废弃的干电池应该集中分类处理
2.(2012黄冈)下列有关“电”的说法正确的是(D)
A.摩擦起电的实质是创造了电荷
B.运动的电荷一定形成电流
C.电路两端有电压就一定有电流
D.电阻中有电流,它的两端一定有电压
二、电压表的连接
自主学习
阅读课本第57、58页,完成下列填空:
测量电路中电压的仪表叫电压表,要测量电路中的电压,必须使它跟这部分电路并联连接,并使电流从正接线柱流入,从负接线柱流出,还要注意被测电压不能超过它的量程.
小组讨论
观察如图所示的电压表的外形,它有V字标记,表盘上有两种刻度,“表座”上有3个接线柱,一个是“-”接线柱,两个正接线柱(3、15),“表头”表盘的示数分别是:(1)0~1~2~3,(2)0~5~10~15,表的正中央有一个调节旋钮.
然后阅读课本上电压表的三个使用特点及图16.1-4,回答下列几个问题:
(1)电压表应该怎样跟被测用电器连接?
(2)电压表的“+”“-”接线柱应该摆在什么位置?
(3)电压表能否直接接到电源的两极?
解:(1)与被测用电器并联;(2)“+”接线柱与电源的正极方向相连,“-”接线柱与电池的负极方向相连;(3)可以.
教师点拨
1.在将电压表连入电路的时候,要同时注意接线柱的连接及量程的选择,不可顾此失彼,更不能将电压表与用电器串联,可将电压表直接接到电源两极上.
2.电压表量程的选择顺序是:
(1)估计被测电路中电压的大小;
(2)在不能估计的情况下,拿电路中的开关试触大量程接线柱;
(3)如果被测电压超过小量程,则选择较大量程,如果在较小量程内则使用较小量程.选择较小量程是为了减小误差.
跟踪练习
1.(2012南昌)请完成下表中两电表正确使用的异同点:
电表
比较
连接方式串联在被测电路中并联在被测电路两端与电源
与电源
相连接绝对不允许不经过用电器直接连在电源两极能直接连在电源两极
相同点使用前都要把指针调到零刻度,弄清分度值,使用时都要选择合适的量程,都要让电流从正接线柱流进负接线柱流出.
2.(2012福州)果汁也能做电池.先向杯中倒入芭乐汁,再把分别接有导线的铜棒和铝棒插入芭乐汁中,作为电池的正负极,如图所示,一个芭乐电池就做成了.那么芭乐电池的正极是铜棒还是铝棒呢?给你电流表、电压表、低压发光二极管、开关各一个,导线若干,请选择其中合适的器材设计一个实验方案进行探究.(也可画图辅助说明)
解:将芭乐电池的铝棒用导线和电流表的负接线柱连接,然后用与铜棒连接的导线跟电流表的正接线柱试触,如果电流表指针正向偏转,说明铜棒是电池的正极;若电流表反向偏转,铝棒是电池的正极.
三、电压表的读数
自主学习
阅读课本第57、58、59页,完成下列填空:
(1)实验室里常用电压表有3个接线柱2个量程.
(2)大量程为0~15V,分度值为0.5V;小量程为0~5V,分度值为0.1V.
(3)读数时,先明确电压表的量程,再确定电流表的分度值,最后看表针向右总共偏了多少小格,就能知道电压的多少.
小组讨论
如图所示的电压表用的接线柱被一片厚布盖着,不知道用了哪两个接线柱与电路连接,我们都知道,电流表的指针向右偏得越多,表示电流越大,但是如图所示的电压到底是多大呢?
思考下列问题:
(1)图中的电压表读数可能有几个?为什么会出现这种情况?
(2)图中电压表有几个量程?它们对应的分度值是多少?二者有什么关系?
解:(1)2个,因为电压表所选的量程没有确定;(2)2个,0.1V和0.5V,大量程的分度值是小量程分度值的5倍.
教师点拨
1.电压表读数时,不要求估读,表针的位置离哪条刻度线近,就按那条刻度线进行读数.
2.某一电压值用大小量程均可测量时,应选用小量程.因为若使用大量程,电压表指针偏转幅度较小,读数不精确.
跟踪练习
1.事先不能估测出电压大小,一般先试用大量程试触,如电压表的示数在小量程范围内,则改用小量程.
2.(2012广东)如图的电压表,若选0~3V的量程,读数为2.6V;若选0~15V的量程,读数为13V.
