Capacitor Charge/Discharge Time Calculator

A capacitor stores electrical energy and the time it takes to charge or discharge is determined by the resistance (R) and capacitance (C). The RC time constant (τ) is given by:

τ = R × C

The voltage across the capacitor during charging:

V(t) = V₀ × (1 – e^-t/τ)

During discharging:

V(t) = V₀ × e^-t/τ

Resistance (R): ΩkΩMΩ
