Capacitor

The capacitor is an element used to store electrical energy in the electrical field. A capacitor is a form of passive energy.

Question

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. Indicate which switches are necessary to start the discharge of the capacitor and why.
