Time Constant (tau) vs Discharge Resistance
सूत्र
## 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).
हल किया गया उदाहरण
100 uF discharging through 10k from 12 V to 1 V.
- 01tau = 10000 x 0.0001 = 1.0 s
- 02t = 1.0 x ln(12/1) = 1.0 x 2.485 = 2.485 s
- 035 tau = 5.0 s to fully discharge
अक्सर पूछे जाने वाले प्रश्न
What is one time constant?
After one tau, voltage drops to 36.8% of initial (1/e).
How many tau to fully discharge?
Practically 5 tau (less than 1% remaining). Theoretically it never reaches exactly zero.
How to discharge faster?
Use a smaller resistance to increase discharge current.
