Answer:(a). The time constant of the circuit is 2.17.(b). The potential difference across the capacitor at t=17.0 s is 0.0396 V.Explanation:Given that,Initial potential difference = 100 VPotential difference across the capacitor = 1.00 V(a). We need to calculate the time constant of the circuitUsing formula of potential differencePut the value into the formulaOn taking ln(b). We need to calculate the potential difference across the capacitor at t=17.0 sUsing formula againHence, (a). The time constant of the circuit is 2.17.(b). The potential difference across the capacitor at t=17.0 s is 0.0396 V....
