to reach 63.2% (for a charging circuit) of its maximum charge capacity given that it has no initial charge. The time constant also defines the response of the circuit to a step (or constant) voltage input. Consequently, the cutoff frequency of the circuit is defined by the time constant....
The time constant is a measurement of the time needed to charge a capacitor by approximately 63.2% or discharge a capacitor by about 36.8% of the difference between the old value and the new value after an impulse that induces a change has been applied. The time constant also defines the ...

3)capacitor/constant current charging power supply电容器/恒流充电电源 4)capacitor charging电容器充电 英文短句/例句 1.The charging of a condenser from a battery is not unlike the filling of a tank from an oil reservoir.电池给电容器充电就象油灌给油箱加油一样。
The time for discharge follows analogous, where the time constant correlates to the charge percentage drop of about 37%. Similar to the charging, the discharging follows an exponential curve as the flowing current decreases over time. After five time constants, the capacitor is considered fully dis...
3) time constant This is the common integralcircuit of R and C series. When the input signal voltage is added to the input,the voltage on the capacitor (C) rises gradually. The charge current decreaseswith the increase of voltage. The current is characterized by the resistance(R) and the...
