电路中含有电流表和电压表以后,电路变得比较复杂。而有关的题目频频出现在中考及各类考试中,能综合考查学生电路知识掌握的水平。解决这类问题的关键是正确认识电表的双重作用,即指示作用和连接作用。一、根据电表的连接作用分析电路电流表和电压表接入电路,特别是多个电流表和电压表连接在电路之后,电路将变得很复杂。为了简化电路,判断用电器的串并
Circuit contains ammeter and voltmeter later, the circuit becomes more complicated. The relevant topics frequently appear in the exam and all kinds of examinations, students can comprehensively test the level of knowledge of the circuit. The key to solving such problems is to correctly understand the dual functions of electric meters, namely, to indicate the role and connection effect. First, according to the connection of the meter to analyze the circuit ammeter and voltmeter access circuit, in particular, a number of ammeter and voltmeter connected to the circuit, the circuit will become very complicated. In order to simplify the circuit, determine the serializer and consumer
