In the circuit at right the capacitor is initially uncharged. R 1. Initially, with the switch in the position shown, what is Q B the potential difference across the capacitor? Explain your answer. V C + 2. At time / = 0 the switch is moved to position A. Draw a graph of the potential difference across the capacitor as a function of time, beginning at =0 and ending a very long time afterward. Be sure to label the initial and final values of the potential difference. 3. After the switch has been in position A for a very long time, it is moved (at time * = 7) to position B. Draw a graph of the potential difference across the capacitor as a function of time, beginning at / = ] and ending a very long time afterward. Be sure to label the initial and final values of the potential difference.4. If you wanted to cause the potential difference across the capacitor to reach its final value more quickly after the switch is moved to position A (without changing the potential difference across the battery), what would you do to the circuit and why would it work? 5. What effect would the change you propose in your answer to question G4 above have on the time it takes the potential difference across the capacitor to reach its final value when the switch is moved to position B (after having been in position A)? Explain your
