 Name: ____________________                                                                                                   Section: ___________________     Capacitance in a Circuit   Part 1:   DATA TABLE: Time (seconds) Voltage (V)                                                 Questions:   Was the voltage across the LED the same as the battery voltage? Why or why not?   How long did it take the voltage across the capacitor to rise to the circuit voltage? Was it instantaneous?   What happened to the voltage when you removed the capacitor from the circuit?  How did the capacitor become discharged?   Part 2:   Questions:   A.    Did the LED light up? Why or why not?   B.     What did the ammeter show when you first closed the circuit?   C.     What did the ammeter show after a few seconds?   D.    How do you explain your observations?     Part 3:     Questions:   A.    What did the voltage across the capacitor do when you first closed the circuit?   B.     Was the voltage across the capacitor the same as the voltage of the battery?   C.     What did the voltage across the capacitor do when you disconnected the battery?
