1.电容器充电结束后,电路中没有电流,与电容器串联的电阻两端电压为零,可按导线处理.2.电容器和部分电路并联,电容器两极板间的电压即为并联部分电路两端的电压.3.电容器连接在“电桥”位置或接在两个独立的电路之间时,可在电路中选择一个共同 1. After the capacitor is charged, there is no current in the circuit, and the voltage across the resistor in series with the capacitor is zero, which can be treated as a conductor. 2. The capacitor and some circuits are connected in parallel. The voltage between the two plates of the capacitor is the voltage at both ends of the parallel section of the circuit. .3. When a capacitor is connected in the “bridge” position or between two separate circuits, one can be selected in the circuit
