A capacitor is connected to an electrical circuit as shown in the image.
The initial voltage of the capacitor will be that obtained when fully charged with all four switches closed.
Then the switches that are required for it to start downloading are opened.
It is known that after 0.1 s in its discharge process, the voltage on the capacitor is 20% of the voltage it initially had.
Questions:
1. Explain how the initial voltage of the capacitor can be calculated.
2. Calculate the initial voltage of the capacitor before it begins to discharge.
3. Say characteristic switches are necessary to initiate the discharge of the capacitor and why.
4. Calculate the value of the capacitance.
