1. 1 Lab #7 – Thevenin/Norton Activity #1 – finding the Thevenin/Norton Equivalent for the function generator –The function generator is a voltage source that produces an AC voltage, usually a sinusoidal voltage. –The waveform produced repeats itself over and over again, in this case 400 times per second

2. 2 BK Function Generator Adjust the frequency knobs to the desired frequency. Select the range Turn on Choose Sine Output terminal Adjust output Voltage

3. 3 Lab #7 – Thevenin/Norton Activity #1 – finding the Thevenin/Norton Equivalent for the function generator –The multimeter is used to measure the RMS (root mean square) voltage (or effective DC voltage because it supplies as much power as a DC voltage source would.) –The DMM can also measure the frequency of the source.

4. 4 Digital Multimeter (DMM) Power switch AC voltage AC current Press the AC voltage button to get the RMS value of AC part of waveform. Range is set automatically

5. 5 Digital Multimeter (DMM) 2ND FREQ You can display the Frequency at the same time by pressing the 2ND button and then pressing the FREQ button.

6. 6 Activity #2 – Max Power Now that you have Rth = R N you can measure the output voltage for different loads and calculate the power delivered to each load.

7. 7 Activities #3-5 – Simulations Find Vth –Find open circuit voltage for Circuit with only independent sources Circuit with both independent and dependent sources –Vth=0 for circuits with only dependent sources

8. 8 Activities #3-5 – Simulations Find Rth –For circuits with only independent sources By source removal, short circuit current or by applying a load –For circuits with only dependent sources Connect a test source to the output –For circuits with both types of sources By short circuit current, by applying a load or by connecting a test source to the output
