Find time constant of circuit
WebThe Time Constant, ( τ ) of the LR series circuit is given as L/R and in which V/R represents the final steady state current value after five time constant values. Once the current reaches this maximum steady state value at 5τ , the inductance of the coil has reduced to zero acting more like a short circuit and effectively removing it from ... WebSep 12, 2024 · The RC time constant is equal to τ = (R + r) = (101Ω)(50 × 10 − 3F) = 5.05s. We can solve the voltage equation for the time it takes the capacitor to reach 80 V: VC(t) = ϵ(1 − e − t / τ), e − t / τ = 1 − VC(t) ϵ, ln(e − t / τ) = ln(1 − VC(t) ϵ), t = − τln(1 − VC(t) ϵ) = − 5.05s ⋅ ln(1 − 80V 100V) = 8.13s.
