一、电流、电压、电阻三者的关系众所周知,电压是形成电流的原因.对于同一导体,当电压升高时,电流会增大;而电阻对电流有阻碍作用,对于同一电路,当增大导体的电阻时,通过导体的电流会减小.因此,探究电流与电压、电阻的关系就成为必然,这对于研究三者之间的定量关系,以及最终得出欧姆定律有着十分重要的意义.电流、电压和电阻三者之间有怎样的关系呢?1.电阻一定时,电流与电压成正比.在描述电流与电压的关系时,不能说成“电阻一定时,电压与电流成正比”.这里存在一个逻辑关系的问题,电流、
First, the current, voltage, resistance, the relationship between the three As we all know, the voltage is the reason for the formation of the current for the same conductor, when the voltage increases, the current will increase; and resistance of the current impede the role of the same circuit, Conductor resistance, the current through the conductor will be reduced.Therefore, to explore the relationship between current and voltage and resistance becomes inevitable, which is very important for the study of the quantitative relationship between the three, and finally come to Ohm’s law. Current, voltage and resistance between the three What is the relationship between? 1 resistance, the current is proportional to the voltage in the description of the relationship between current and voltage can not be said “resistance is constant, the voltage and current is proportional to ”There is a logical relationship here, the current,
