用Tracker视频分析软件研究电容器的充放电过程

Study on the Process of Charging and Discharging of a Capacitor Using Tracker Video Analysis Software

设计了用Tracker视频分析软件研究电容器的充放电过程,分别研究了电路中的电阻、电容与充放电时间之间的关系.其次,分别验证了串联电容电路和并联电容电路中电容的大小关系以及电容两端电压、电荷量、电容之间的大小关系.

The process of charging and discharging of a capacitor was studied by Tracker software.The relationship among the resistance,capacitance and the time of charging and discharging of a capacitor in the circuit was discussed.Moreover,the relationship between total capacitance and partial capacitance in series or parallel circuits,and the relationship among the voltage,quantity of electric charge and the capacitance were verified in respectively.
