1、高考物理知识点总结复习：串联电路和并联电路知识要点：1部分电路基本规律（1）形成电流的条件：一是要有自由电荷，二是导体内部存在电场，即导体两端存在电压。（2）电流强度：通过导体横截面的电量q 跟通过这些电量所用时间 t 的比值，叫电流强度：。（3）电阻及电阻定律：导体的电阻反映了导体阻碍电流的性质，定义式RUI；在温度不变时，导体的电阻与其长度成正比，与导体的长度成正比，与导体的横截面 S成反比，跟导体的材料有关，即由导体本身的因素决定，决定式RLS；公式中 L、S是导体的几何特征量，叫材料的电阻率，反映了材料的导电性能。按电阻率的大小将材料分成导体和绝缘体。对于金属导体，它们的电阻率一般都与

2、温度有关，温度升高对电阻率增大，导体的电阻也随之增大，电阻定律是在温度不变的条件下总结出的物理规律，因此也只有在温度不变的条件下才能使用。将公式RUI错误地认为 R 与 U 成正比或 R 与 I 成反比。对这一错误推论，可以从两个方面来分析：第一，电阻是导体的自身结构特性决定的，与导体两端是否加电压，加多大的电压，导体中是否有电流通过，有多大电流通过没有直接关系；加在导体上的电压大，通过的电流也大，导体的温度会升高，导体的电阻会有所变化，但这只是间接影响，而没有直接关系。第二，伏安法测电阻是根据电阻的定义式RUI，用伏特表测出电阻两端的电压，用安培表测出通过电阻的电流，从而计算出电阻值，这是测

3、量电阻的一种方法。（4）欧姆定律通过导体的电流强度，跟导体两端的电压成正比，跟导体的电阻成反比，即IUR，要注意：a：公式中的 I、U、R 三个量必须是属于同一段电路的具有瞬时对应关系。b：适用范围：适用于金属导体和电解质的溶液，不适用于气体。在电动机中，导电的物质虽然也是金属，但由于电动机转动时产生了电磁感应现象，这时通过电动机的电流，也不能简单地由加在电动机两端的电压和电动机电枢的电阻来决定。（5）电功和电功率：电流做功的实质是电场力对电荷做功，电场力对电荷做功电荷的电势能减少，电势能转化为其他形式的能，因此电功 W=qU=UIt，这是计算电功普遍适用的公式。单位时间内电流做的功叫电功率P

4、WtUI，这是计算电功率普遍适用的公式。（6）电热和焦耳定律：电流通过电阻时产生的热叫电热。Q=I2 R t 这是普遍适用的电热的计算公式。电热和电功的区别：a：纯电阻用电器：电流通过用电器以发热为目的，例如电炉、电熨斗、白炽灯等。b：非纯电阻用电器：电流通过用电器以转化为热能以外的形式的文档编码:CV8Q9C3N5A9 HX7N3X4U9B1 ZV2R6Y4M7A1文档编码:CV8Q9C3N5A9 HX7N3X4U9B1 ZV2R6Y4M7A1文档编码:CV8Q9C3N5A9 HX7N3X4U9B1 ZV2R6Y4M7A1文档编码:CV8Q9C3N5A9 HX7N3X4U9B1 ZV2R6Y

11、。在纯电阻电路中，电能全部转化为热能，电功等于电热，即 W=UIt=I2Rt=URt2是通用的，没有区别。同理PUII RUR22也无区别。在非纯电阻电路中，电路消耗的电能，即W=UIt 分为两部分：一大部分转化为热能以外的其他形式的能（例如电流通过电动机，电动机转动将电能转化为机械能）；另一小部分不可避免地转化为电热Q=I2R t。这里 W=UIt 不再等于 Q=I2Rt，而是 W Q，应该是 W=E其他+Q，电功只能用 W=UIt，电热只能用 Q=I2Rt 计算。2串联电路和并联电路（1）串联电路及分压作用a：串联电路的基本特点：电路中各处的电流都相等；电路两端的总电压等于电路各部分电压之
