摘　　要：运用能够输出正负对称方波电压的信号发生器频率可调的特性，改变方波电压的频率，以达到改变RC暂态电路的充放电时间的目的，可在示波器上观察到不同时间常数的RC电路充放电过程中电容器两端的电压、电路中充放电电流的波形图。In this paper,we use the adjustable characteristics of frequency in signal generator which can output positive and negative symmetric square-wave voltage,changing the frequency of the square-wave voltage to achieve the purpose of changing the time of charging and discharging in the RC transient circuit.Thus,on the oscilloscope,we can observe the charging and discharging current waveform diagram of voltage and circuit in capacitor during the charging and discharging of different time constant in RC circuit.
