A supercapacitor is an electrical energy storage device. A supercapacitor, initially charged to 9.8 thousand millivolts, supplies power to an emergency beacon. The power draw from the load causes the capacitor to lose 4.4% of its charge every minute. When the charge drops below 7 hundred millivolts the beacon will cease functioning. How long will the beacon last after it is activated (your final answer should be in minutes). Round your answer to the nearest minute.

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.
