Prob. 10-15: RMS of a waveform - 04/29/2015

Prob 10-10 real and reactive power

Three phase example

Problem 9.29 AC Steady State

You can also do this problem using phasers (magnitude and phase)

iPad return on Friday after the Final Exam

Please be sure to bring the USD iPad and power cord (and whatever else they issued to you) on Friday. A representative of the USD IT department will be in class toward the end of the final exam period to collect the iPads.

I'll send out another reminder this evening.

Thanks --DK

Final exam

The final exam will commence at 10:20 AM on Friday, 1 August. It will end at 12:00 noon.

You will be asked to solve problems in:

• Ideal Transformer - Study the transformer presentation
• Complex Power - know what apparent power, real power, and reactive power are. Be sure that you know the I and V equations to arrive at the apparent power, real power, and reactive power. know how to correct for power factor.
• Steady-state AC circuit analysis using impedances.
• Second order circuits.
• A simple three phase problem
•  Mesh Current or Node Voltage circuit analysis.

Good Luck!

Two surveys on Survey Monkey

Please complete the two surveys on Survey Monday. I sent the URLs to your USD email addresses.

One survey is on your use of the issued iPad. The other survey is your assessment of the "flipped classroom".

Please complete the survey by end of business on Friday, 1 August 2014. Thanks!
