1.探究欧姆定律的实验在探究欧姆定律的实验中,我们主要研究电流跟电压、电阻的关系.由于电流受电压、电阻两个因素的影响,因此,实验采用控制变量法.即"保持电阻不变,研究电流跟电压的关
1. Exploring Ohm’s law experiment In the experiment of exploring Ohm’s law, we mainly studied the relationship between current and voltage and resistance. Since the current is affected by voltage and resistance, the experiment adopts the control variable method. The resistance does not change and the current and voltage are studied.
