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 V
Potential difference across the capacitor = 1.00 V
(a). We need to calculate the time constant of the circuit
Using formula of potential difference
Put the value into the formula
On taking ln
(b). We need to calculate the potential difference across the capacitor at t=17.0 s
Using formula again
Hence, (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.
