Measurement the Norton Equivalent for the circuit between node A and Ground in Multisim

Full Answer Section

1. Simulate the circuit and record the current and voltage readings.

2. Use the following equation to calculate the Norton Equivalent current (I_N):

I_N = I - I_S

where I is the current flowing through the circuit and I_S is the short-circuit current.

8. Use the following equation to calculate the Norton Equivalent resistance (R_N):

R_N = V / I_N

where V is the voltage across the circuit and I_N is the Norton Equivalent current.

9. Repeat steps 6-8 for different values of the current source.

10. Plot the Norton Equivalent current (I_N) versus the Norton Equivalent resistance (R_N).

11. The Norton Equivalent for the circuit between node A and Ground is the point where the line intersects the y-axis.

Here is an example of how to determine by measurement the Norton Equivalent for the circuit between node A and Ground in Multisim:

1. Open Multisim and create a new schematic.

2. Draw the following circuit:

A
|
R1
|
B
|
V1
|
Ground

where R1 is a 1 kΩ resistor and V1 is a 1 V voltage source.

3. Connect a current source (I) to node A and a voltage source (V) to Ground.

4. Connect an ammeter (A) to measure the current flowing through the circuit.

5. Connect a voltmeter (V) to measure the voltage across the circuit.

6. Simulate the circuit and record the current and voltage readings.

7. I = 1 mA and V = 0.99 V.

8. I_S = 0 mA.

9. I_N = I - I_S = 1 mA - 0 mA = 1 mA.

10. R_N = V / I_N = 0.99 V / 1 mA = 990 Ω.

11. Repeat steps 6-10 for different values of the current source.

12. Plot the Norton Equivalent current (I_N) versus the Norton Equivalent resistance (R_N).

13. The Norton Equivalent for the circuit between node A and Ground is the point where the line intersects the y-axis. The Norton Equivalent current is 1 mA and the Norton Equivalent resistance is 990 Ω.
