A source-free RC contains an initially charged capacitor with voltage Vo. What is the voltage across this capacitor after a time of t = 17 has elapsed where t is the time constant.

All capacitors were initially discharged.at t = 0, S1 is placed at position 1 and S2 is closed.At t = 15 ms, S1 is placed at position 2 and S2 is kept closed. At t = 25 ms, S1 is kept at position 2 and S2 is opened.after 25 ms, the voltage vT will Question options: increase until it reaches the battery voltage at steady state exponentially decay to zero stay constant be a sine wave
