Question

Hello could you please find these variables in this experiment?

Could you please write the reasons why they are independent, fixed and dependent varialbe?

a) Identify the independent variable(s) in this experiment. Be specific and use proper vocabulary.

b) Identify the fixed variable(s) in this experiment. Be specific and use proper vocabulary.

c) Identify the dependent variable(s) in this experiment. Be specific and use proper vocabulary.

Here is procedure.

PROCEDURE:

1. Connect the three resistors, specified by the instructor, in series. Measure its equivalent resistance.

2. Start up the laptop and open the PHYS 4B LABS folder on the desktop.

3. Double-click on the VI Sensor.cap file.

4. Assemble the series circuit with these resistors. And find equivalent resistance with using Digital Multimeter (DMM).

5. Set the power supply to 9.50 Volts.

6. Click on the “Record” button to begin recording data.

7. Measure the voltage drop of, and the current through, each resistor in the series circuit. Make sure to turn off the power supply BEFORE moving the current sensor’s location in the circuit.

8. Disconnect the circuit and turn off the power supply.

9. Connect the three resistors, specified by the instructor, in parallel. Measure its equivalent resistance.

10. Assemble the parallel circuit with these resistors. And find equivalent resistance with using Digital Multimeter (DMM).

11. Set the power supply to a voltage where the battery current is 20 mA.

12. Measure the voltage drop of, and current through, each resistor in the parallel circuit. Make sure to turn off the power supply BEFORE moving the current sensor’s location in the circuit. 13. Turn off the power supply.

14. Connect the three resistors, specified by the instructor, in a series-parallel connection. Measure its equivalent resistance.

15. Reset the power supply back to 9.50 Volts.

16. Assemble the series-parallel circuit with these resistors. And find equivalent resistance with using Digital Multimeter (DMM).
17. Measure the voltage drop of, and current through, each resistor in the series-parallel circuit. Make sure to turn off the power supply BEFORE moving the current sensor’s location in the circuit.

18. Read through and answer the first question in the QUESTIONS section below.

(Construct a circuit, using one of each of the resistors in this experiment, where the circuit voltage is 10.00 V and the battery current is 75 mA. Show this to the instructor to earn credit for this problem)

19. Turn off the power supply and disconnect the circuit.

Explanation / Answer

1) Three resistors connected in series are fixed variable as we need to chose the resistors as specified by the instructor.

2) Power Supply used is independent variable as the voltage cab be set to any other value also.

3) The current throgh each resistor are dependent variable and depends on the resistor values and voltage supplied.

4) Voltage drops through each resistors are.dependent variable as they depends on the value of resistor through which it is calculated.

5) The current supplied(20mA) in the second when resistors are connected in parallel is an independent variable and can be varied.

6) Equivalent resistance of resistors in parallel is dependent variable and are dependent on the value of three resistors selected.

7) Voltage drop across each resistors are dependent variables and depends on current supply and and the value of resistor through which it is calculated.

8) In Series parallel circuit voltage supplied is independent variable.

9) Equivalent resistance is again dependent variable and depends on values of resistors.

10)Voltage drop across each resistor is a dependent variable as they depend on value of resistor through which it is calculated.

11) Current flowing is dependent variable and depends on values of resistors and voltage supplied.

12) In final condition Voltage and current flowing are fixed variables. The resistor values are independent values but equivalent resistance of the circuit is a fixed value. And Voltage drop across each resistor are dependent values depends on resistor value through which it is calculated.
