Detailed Solution
Download Solution PDFTime constant:
- The time constant is always calculated for the circuit at t>0.
- The time constant for an RC circuit (τ) = \(R_{eq}C\)
- The time constant for an RL circuit (τ) = \( {L \over R_{eq}}\)
Calculation:
\(R_{eq}= {2R\times R \over 2R+R}\)
\(R_{eq}= {2R^2 \over 3R}\)
\(R_{eq}= {2R \over 3}\)
\(τ = R_{eq}C\)
\(τ= {2R\over 3}\times C\)
τ = \(\frac{{2RC}}{3}\)
