Simulation Problems Lab 4

• Install SIMetrix elements

• The process of running a simulation:

✓Build a circuit

✓Apply Rule #9

✓Set up the transient simulation

✓Run the simulation

✓Plot the voltages and currents

✓Analyze the results- think about the so what?

Example 1 RC Charging

• Simple RC charging circuit

• Follow along in the video for the RC circuit

Example 2: RL

• Follow along the video for the RL circuit simulation

Example 3: Series RLC

• Follow along with the video on the series RLC circuit

Assignment Lab 4

• Create a series RLC circuit with

✓ L = 1 uH, C = 1 uF

• Determine R for underdamped with a Q of about 10

• Anticipate what you expect for the voltage across the C:

✓ Number of cycles of ringing

✓ Period of the oscillations

• Simulate the voltage across the C over a time period to see at least the 10 oscillations before they die out.

• Show an example of underdamped, with a Q of 10, critically damped and over damped. Turn in a 1 page pdf summary: (pix and a few sentences)

✓ Provide a screen shot of your circuit and the simulated voltage waveforms

✓ Analyze the result: what is the period compared to what you expected? what is the ringing compared to what you expected?
