## RC Discharge Timing
**tau = R x C**
**V(t) = V_0 x e^(-t/tau)**
**t = tau x ln(V_0 / V_target)**
After 5 time constants, the capacitor is essentially discharged (< 1% of initial).
**tau = R x C**

计算示例
100 uF discharging through 10k from 12 V to 1 V.
- tau = 10000 x 0.0001 = 1.0 s
- t = 1.0 x ln(12/1) = 1.0 x 2.485 = 2.485 s
- 5 tau = 5.0 s to fully discharge
