2. If the capacitor in Q 1 is charged to a potential difference of 12 V, then discharged through an 0.8 MΩ resistance as shown?

a- What is the time constant of the circuit?






b- What is the initial charge on the capacitor?
c- Find the voltage across the capacitor after one time constant.
d- What is the final charge on the capacitor after very long time?

Nobody can do this, because it was probably in "Question 1" that the capacitance of the device was specified.
