Using the equivalent resistance and capacitance formulas, what is the time constant \( \tau=R_{e q} C_{e q} \) in seconds for this charging circuit where the charge as a function of time is given by \( q(t)=Q\left(1-e^{-\frac{t}{\tau}}\right) \) ? There are two resistors and capacitors as shown, each with say resistance \( \mathrm{R}=1 \mathrm{ohm} \) and capacitance \( \mathrm{C}=1 \) farad respectively.
