辕哑士3675高中物理,限流电路与分压电路有什么区别,这些选择原则是怎么出来的? -
祖背皇19690198506 ______[答案] 第一点:如果待测电阻的阻值远大于滑动变阻器的最大阻值,那么,若选择限流电路,则滑动变阻器对电路电流的改变不明... 第三点:若选择限流式接法,电路中的最小电流仍超过用电器的额定电流,说明用电器两端的电压过大,此时应选择分压式...

辕哑士3675分压电路和分压限流电路.他们有什么区别.使用条件各是什么. -
祖背皇19690198506 ______[答案] 1、描绘小灯泡的伏安特性曲线时,要求电压和电流必须从零开始测量,就必须用分压式.可以归结为:施药中要求从零开始测量的,就必须用分压式. 2、如果整个电路中,滑动电阻器比较小,对整个电路几乎没有影响的,也必须用分压式.例如:测量...

辕哑士3675限流式与分压式实物图的滑动电阻器有什么不同 -
祖背皇19690198506 ______[答案] 限流式与分压式所用的都是滑动变阻器,实物图上没有区别,两种方式的区别主要在如何连接电路上. 限流式中:滑动变阻器是串联在电路中的,链接两个点(上接线柱一个,下接线柱一个) 限压式中:滑动变阻器是并联在电路中的,连接三个点(...

辕哑士3675.滑动变阻器的分压式和限流式接法的含义是什么..怎么区分我大概懂了.但限流式不是串联的么串联不是分压么.而分压式是并联的,不应该是分流么? -
祖背皇19690198506 ______[答案] 滑动变阻器的分压式接法—— 用两条输电线将电源电压加在滑动变阻器的整个电阻的两端,再用两条输电线将滑片某一侧的电压输给用电器——将总电压的一部分输给用电器(是分一部分电压给用电器的意思,故称为分压式). 滑动变阻器的限流式...

辕哑士3675电路中的限流式和分压式的区别? -
祖背皇19690198506 ______ 限流是限制电流量,即并联一个电阻分流,而分压是串联一个电阻分压

辕哑士3675限流式和分压式的区别 -
祖背皇19690198506 ______ 简单点,就是看电流表在哪里.若是在电压表两端外则是分压,两端内则是限流.

辕哑士3675限流式,分压式的区别.哪些地方用限流式,哪些地方用分压式? -
祖背皇19690198506 ______[答案] 一般先判断是否要用分压式,有三种必须要选分压.1、从题意看需要电压或电流从零开始2、滑动变阻器串联接入调节时,电表示数变化范围很小3、滑动变阻器串联接入调节时,电表示数总是超过量程.其余的都用限流,因为结构简单,耗能少.

辕哑士3675物理分压 限流式电路区别简单说一下 -
祖背皇19690198506 ______ 分压电路是与滑动变阻器串联 限流电路是与滑动变阻器并联 区别是分压不令电压变0 而限流可以从0开始

辕哑士3675物理实验中分压法与限流发的区别,什么情况下用? -
祖背皇19690198506 ______[答案] 当被测电阻远大于变阻器电阻时,此时通俗的说,装个变阻器对电路的控制不大,因此此时应该用能尽量控制电表范围的分压式接法.当两者阻值差不多时,可根据实验提供的器材选限流式

辕哑士3675高二物理滑动变阻器分压和限流有什么区别怎么区分这两种接法,各有什么特点,最好有例子,今晚就要, -
祖背皇19690198506 ______[答案] 1.限流式——主要用于待测用电器电阻接近滑动变阻器电阻(不是绝对的)和简化电路,节约能源:滑动变阻器实际上是串联在线路中的,因此起到了限流的作用,所以称之为限流式;2.分压式——待测用电器电阻远大于或远小于...
