Capacitor Energy and Time Constant Calculator
This calculator computes the energy in a capacitor, given the voltage across it.
If you specify a load resistor it will also compute the time constant, or the time until the voltage drops to 37%, or charges to 63%.
See our standard resistor calculator for a real world resistor value.
Equations:
E= V^2*C/2
TC= R*C
1/e = 36.8%
电容器能量和时间常数计算器
该计算器根据电容器两端的电压来计算电容器中的能量.
如果您指定负载电阻,它还将计算时间常数,或者电压降至 37% 或充电至 63% 的时间.
请参阅我们的标准电阻计算器以了解实际电阻值.
方程式：
E=V^2*C/2
TC=R*C
1/e = 36.8%
