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.

In the diagram below, the switch S has been closed for a long time. A) What is the output voltage Vout? What is the charge on the capacitor? b) The switch is opened, so the output voltage increases. What is the time constant that describes the charging of the capacitor in terms of R and C? c) When Vout reaches 10 V, the switch closes and the capacitor begins to discharge. What is the time constant that describes the discharging in terms of R and C? Hint: Apply Kirchhoff's Rules to both loops and the sum of the currents at the junction above the capacitor in the diagram, and use I=dq/dt. If the switch opens when Vout reaches a lower value, say 5V, the capacitor will charge again, and thus one can cycle the voltage with a time constant determined by the circuit: this demonstrates the principle of operation of an electronic timer. 4R S 15 V Vout R
