\text { In Figure } 14.12, \quad \varepsilon=12 \mathrm{V}, \quad L=20 \mathrm{mH}, \quad \text { and } $R=5.0 \Omega .$ Determine (a) the time constant of the circuit, (b) the initial current through the resistor, (c) the final current through the resistor, (d) the current through the resistor when $t=2 \tau_{L}, \quad$ and $(\mathrm{e})$ the voltages across the inductor and the resistor when $t=2 \tau_{L}$.
The circuit in the figure below has been connected for a long time. Let R1 = 8.40 ̐ and R2 = 5.60 ̐. (a) What is the potential difference across the capacitor? (b) If the battery is disconnected from the circuit, over what time interval does the capacitor discharge to one-half its initial voltage? Your response differs from the correct answer by more than 10%. Double-check your calculations.
