+5V로 S1 S2 4.7 ΚΩ www 850 µF In the above circuit the capacitor is fully discharged. Switch S2 is initially open, and S1 is closed for 3.5 seconds, then reopened. Switch S2 is then closed for 2.0 seconds, then reopened. What is the voltage across the capacitor after S2 is reopened? Show your answer in volts to two decimal places.
