Harmonics
What effects could be experienced as a result of harmonics within
1) star transformer systems
2) delta transformer systems
3) a.c motors
4)Describe the term K factor
5) To imrove the power factor a capacitor bank has been
installed. What effects would this have on the harmonics
In the following graph of a sine wave, the Y-axis is voltage (Volts) and the X-axis is time seconds). What is the voltage amplitude? What is the phase shift in seconds?What is the phase shift in degrees?What is the phase shift in radians?
1.) Explain the difference between a time domain signal and a
frequency domain signal.
2.) When would you select the frequency domain signal over the
time domain signal.
How
would Plato account for the nature of a square (i.e. what makes a
square a square according to Plato)? What would make a table a
table for Plato? How do you think Plato would explain a table
changing (e.g. breaking, being destroyed in a fire, being used as
material to make a chair)?

a. What is the electron-domain (charge-cloud) geometry of BrF5?
Enter the electron-domain geometry of the molecule.
b. What is the molecular geometry of BrF5?
c. Ignoring lone-pair effects, what is the smallest bond angle
in BrF5?
d. Which choice best describes the polarity of BrF5?
The molecule is polar and has polar bonds.
The molecule is nonpolar and has polar bonds.
The molecule is polar and has nonpolar bonds.
The molecule is nonpolar and has nonpolar bonds.

1)What is the advantage of solving differential equations using
Laplace Transforms over prior time-domain techniques cover thus far
this semester (Chps 1-5)?
2) When using Laplace Transforms, what is the difference in the
notation between lower case (i.e. f(t)) and upper case (i.e. F(s))
letters?
3) If the Laplace Transform is an integral as shown in Sec 7.1,
pg 438, equation #1, how can Dr. Tran claim that the Laplace
Transform technique does not require use of Calculus? Is he...
