贡俭安2546路端电压是什么东东? -
相和骆15196896956 ______ 输出所得的电压,因为电源内阻的原因,电源也要分得一些相应的电压,于是路端电压就=电源电压-内端电压,总之路端电压小于电源电压,电池用久了输出电压降低就是这个原因.

贡俭安2546高中物理路端电压一定是干路当中的电压吗? -
相和骆15196896956 ______ 端电压是外电路的总电压,干路的电压概念很模糊,如果有并联电路时,干路电流是指各并联电路的总电流,并联电路的电压和干路的电压不是一回事.而此时的路端电压应该等于那个干路的电压和并联电路的总电压.

贡俭安2546(高二物理)请教电源电压与路端电压的区别?1 请问 电源电压与路端电压 到底有什么区别呢?在一个闭合电路中一般来说,其中哪个电压是固定不变的呢... -
相和骆15196896956 ______[答案] 其实是内阻的问题,也就是说实际中用的电源都有一定的内阻,可以理解成一个纯电源跟一个很小的电阻串联就是我们平常用的电源了 所说的电源电压其实就是路端电压了,不知道你问的是不是电动势与路端电压的问题,因为在高二阶段这两个概念...

贡俭安2546路端电压不是外电压吗?怎么练习书上写是路端电压是电源电压(内电压)?
相和骆15196896956 ______ 外电路断开的时候路端电压是电源电动势,你的理解没错

贡俭安2546为什么电压表接在闭合回路中的电源两端时会测得路端电压而不是电源电压? -
相和骆15196896956 ______[答案] 因为我们使用的电源不是理想电源,有内阻的存在,E=U+Ir,式中E表示电源电动势,U表示路端电压,Ir表示内阻分得的那部分电压,我们将电压表接在电源两端时,测出的是路端电压,小于电源电压

贡俭安2546关于路端电压的问题这两天高中初学 请问当电路只接了一个用电器(电阻)时 路端电压是否等于电源内部电压 .还有 接在两端的电压表测的是路端电压还是电... -
相和骆15196896956 ______[答案] 当电路只接了一个用电器(电阻)时,路端电压不等于电源内部电压,而是等于电源电压减去内阻上的电压分压(称为电压降). 接在两端的电压表测的是路端电压,不是电源内压!

贡俭安2546路端电压是什么 -
相和骆15196896956 ______ 路端电压,也就是外电路两端的电压,通常叫做路端电压(Terminal Voltage),也可称为外电路电压(外电压).

贡俭安2546物理学中电压是什么?
相和骆15196896956 ______ 电源电压即电动势,路端电压即电动势减去电源的内压,即外电路的电压. 电源电压一般不变,路端电压根据电源的内阻来定. 所说的电源电压其实就是路端电压了,不知道你问的是不是电动势与路端电压的问题,因为在高二阶段这两个概念会很容易混 电动势就是刚才说的那个纯电源的电压(只是理解成这样,不是概念) 内部的电阻跟外部电路一定是串联关系,串联分压,施加在外部电路的电压就是路端电压,或者说电源电压 至于闭合电路电流,由内阻r,外部电阻R和电动势E决定,即I=E/(r+R),再由U=IR得到路端电压(闭合电路欧姆定律)谢谢采纳

贡俭安2546电源的路端电压指的是什么?
相和骆15196896956 ______ 电源的路端电压是指电源加在外电路两端的电压,是静电力把单位正电荷从正极经外电路移到负极所做的功

贡俭安2546电源&闭合电路的欧姆定律 1.电源电压和路端电压是什么关系?他俩是一个概念吗?为什么看到有说电源电压是内压降的?2.电压表并联在电源两端,为什... -
相和骆15196896956 ______[答案] 电源相当于一个理想电压源与一个电阻串联 路端电压相当于电阻电源与理想电源电压之和 当在电源两端接电压表时 电流为0时 测得电源电压 电流不为0时 测得路端电压 当开路时 不存在路端电压一说
