Question

Circuit Current vs. Time 20.00 R + S2 C 10.00 S1 30.00 -3 10.00 20.00 00 Ao o Time (s) x10 Current (Amp)

This lab involves an animation of an RC circuit. By clicking on the connect battery link below the animation, you close switch 1 and open switch 2 connecting a 40V battery to the resistor and capacitor in series. By clicking on the disconnect battery link, you close switch 2 and open switch 1 eliminating the battery from the circuit and connecting the resistor and capacitor in series. On the right hand side a graph of the current vs. time through the resistor is shown.

1) Immediately after the battery is connected, what is the voltage across the resistor?
     0 V
     10 V
     20 V
     30 V
     40 V

2) What is the resistance of the resistor?
     1 ohm
     2 ohms
     3 ohms
     4 ohms

3) After the battery has been connected for a long time, what is the voltage across the capacitor?
     0 V
     10 V
     20 V
     30 V
     40 V

4) Immediately after the battery is disconnected, what is the voltage across the resistor? Explain.
     0 V
     10 V
     20 V
     30 V
     40 V

5) Immediately after the battery is disconnected, what is the voltage across the capacitor? Explain.
     0 V
     10 V
     20 V
     30 V
     40 V

6) After the battery has been disconnected for a long time, what is the voltage across the resistor? Explain.
     0 V
     10 V
     20 V
     30 V
     40 V
