Charging a Capacitor

给电容器充电

When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other. The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage. Charging the capacitor stores energy in the electric field between the capacitor plates. The rate of charging is typically described in terms of a time constant RC.

当电池连接到一个电阻和电容器串联电路中时,初始电流很高,因为电池将电荷从电容器的两极板之间传输。充电电流逐渐趋近于零,随着电容器被充电至电池电压。充电电容器会在电容器板之间的电场中储存能量。充电速率通常以时间常数RC来描述。
