The Circuit Construction Simulator Assignment
 1.  Go to this web site to open the Circuit Development Simulator:http://phet.colorado.edu/en/simulation/circuit-construction-kit-dcIf you cannot get the simulation to run instantly, please verify the next:Ensure you have Java put in and up to date. https://www.java.com/confirmEnsure that your safety settings (Apple Menu > System Preferences > Safety & Privateness > Common tab) enable apps downloaded from wherever. You may change this again after working the simulation if you want.Click on and drag one battery, two resistors, and 7 wires from the white field to the left of the display screen.Prepare the items right into a circuit with the battery on prime and the 2 resistors on the underside: "LOOK AT PICTURE 1-1" (ATTACHED)Click on on the battery and use the slider to vary the voltage to 9.0V.Click on on the left resistor and alter the worth to 10 Ohms.Click on on the precise resistor and alter the worth to 20 Ohms."LOOK AT PICTURE 1-2" (ATTACHED)Click on the non-contact ammeter button in the midst of the inexperienced field. Place the crosshairs of the non-contact ammeter on the wire a number of locations across the circuit to search out the present within the wire.  What's it? " LOOK AT PICTURE 1-Three" (ATTACHED)
  • zero.15 A
  • zero.30 A
  • zero.45 A
  • zero.60 A
2. Is that this circuit organized in collection, in parallel, or in each formations?
  • Sequence
  • Parallel
  • Each collection and parallel
Three. Based mostly in your reply from #2, use one of many following equations to calculate the overall resistance of the circuit.Resistance in collection:Rtotal=R1+R2Resistance in parallel:1/Rtotal=1/R1+1/R2
  • 6.67 Ohms
  • 10 Ohms
  • 20 Ohms
  • 30 Ohms
four. Now, utilizing Ohm's Regulation:I=V/Rand the overall resistance calculated in #Three, what's the whole present of this circuit?
  • zero.15 A
  • zero.30 A
  • zero.45 A
  • zero.60 A
5. Click on the voltmeter.  A voltmeter measures the distinction within the voltage between 2 locations on a circuit. That is known as the voltage drop. Place the contacts of the voltmeter on the circuit on both aspect of the battery.Word: The voltmeter tells you the voltage drop between the 2 factors within the circuit touched by the probes.Voltage works similarly to gravitational potential power primarily based on top.  Balls will solely roll down board if one finish is larger than the opposite (so it's sloped). The ball (electron) on the larger finish of the board (wire) has a number of potential power (voltage). The ball will roll down the board (electron will transfer by way of the wire) to the decrease finish of the board that has much less gravitational potential (much less voltage). You might use a ruler to measure the peak distinction between the excessive level of the board and the low level the place the ball strikes to. This may be the change in top or how exhausting the ball dropped in top. For the electron, you'd use a voltmeter to measure how a lot the voltage dropped from one level to a different.  "LOOK AT PICTURE 5 (ATTACHED)"What's the voltage drop throughout the battery?
  • 1 V
  • Three V
  • 9 V
  • 12 V
6. Place the contacts on both aspect of the 10 Ohm resistor.What's the voltage drop throughout the 10 Ohm resistor?
  • Three.zero V
  • four.5 V
  • 6.zero V
  • 9.zero V
7. What's the voltage drop throughout the 20 Ohm resistor?
  • Three.zero V
  • four.5 V
  • 6.zero V
  • 9.zero V
eight. Add collectively your solutions from #6 and #7.  Is that this quantity larger than, lower than, or equal to the voltage of our battery?
  • Larger than
  • Lower than
  • Equal to
9. Change the voltage of the battery from 9 V to 15 V by Ctrl-clicking on the battery and deciding on “Change voltage”.Use the voltmeter to remeasure the voltage throughout every of the resistors.  Now how does the overall voltage throughout the resistors examine to that of the battery?Word: If you happen to obtain decimal factors for any of your voltmeter readings, please spherical to the closest complete quantity earlier than including and evaluating.
  • Larger than
  • Lower than
  • Equal to
10. Change the battery’s voltage again to 9 Volts, use three extra wires, and rearrange your resistors in order that the circuit is ready up like this" LOOK AT PICTURE 10  (ATTACHED)Is that this circuit organized in collection, in parallel, or in each formations?
  • Sequence
  • Parallel
  • Each Sequence and Parallel
11. Based mostly in your reply in #10, use one of many following equations to calculate the overall resistance of the circuit:Resistance in SequenceRtotal=R1+R2Resistance in Parallel1/Rtotal=1/R1+1/R2
  • 6.67 Ohms
  • 10 Ohms
  • 20 Ohms
  • 30 Ohms
12. Now, utilizing Ohm's Regulation:I=V/Rand the overall resistance calculated in #11, what's the whole present of this circuit?
  • 1.35 A
  • zero.90 A
  • zero.45 A
  • zero.30 A
13. Utilizing the non-contact ammeter, what's the present by way of the trail with the 20 Ohm resistor?
  • 1.35 A
  • zero.90 A
  • zero.45 A
  • zero.30 A
14. Once more, utilizing the non-contact ammeter, what's the present by way of the trail with the 10 Ohm resistor?
  • 1.35 A
  • zero.90 A
  • zero.45 A
  • zero.30 A
15. Add your reply for #13 and #14 collectively.  What is critical about this quantity?
  • This is the same as the overall present you present in #12.
  • That is lower than the overall present you present in #12.
  • That is larger than the overall present you present in #12.
