一、在电学实验中,同学们对复杂电路中电压表在电路中的连接方法及所量的用电器的电压读数出现偏差1.把电压表当成通路混淆了电路中串并联的连接方法 ,即容易把串联电路误认为并联电路。2.电压表所测电压的示数学生分不清是哪个用电器两端的电压,甚至把电源电压当成是用电器两端的电压。因此,教师在上课过程中,首先让学生把电压表去掉,这样复杂电路就简单一些,画好等效电路图后,分清这是并联电路还是串联电路,然后再把电压表装上。如果仍旧搞不清电
First, in electrical experiments, the students on the complex circuit voltage meter in the circuit connection method and the amount of electrical voltage reading deviation 1. The voltmeter as a pathway confused the circuit series and parallel connections, that is, Easily mistaken for a series circuit in parallel circuit. 2 voltmeter measured voltage shows the number of students can not tell which is the voltage across the appliance, and even the supply voltage as the voltage across the appliance. Therefore, the teacher in class, first of all let the student to remove the voltmeter, so complex circuit is simpler, draw the equivalent circuit diagram, distinguish this is the parallel circuit or series circuit, and then put on the voltmeter. If you still can not figure out electricity
