*Mr. Wirth wonderfully volunteers me to be scribe. . .
10:47AM
*Begin going over the homework
Example work for #3-
Given Info:
q = 220 C
v = 220 V
t = 4 sec
ESA work:
P = VI
P = V [(delta q)/t]
P = (2200 C)(220 V) /(4 s)
P = 12,100 W
10:55 AM
*Begin notes
*Analyzing Circuits
-several different configurations
-branches
-involves Ohm's Law (applies to circuit and individual resistors)
***Equivalent Resistance: The Resistance Seen By The Source***
R(eq) = V(source) / I (source)
10:58 AM
*Talk about Next Week
-will apply these principals to several different circuit configurations
10:59 AM - 11:00 AM
*Talk about new cell phone policy and pass out the review set #1
11:07 AM
*Still working on review set
11:25 AM
*class ends; have a nice weekend :)

This is very informative and precise. DH you are an amazing person.
D,
Nice job, and thank you for graciously "volunteering"!
March 27, 2008
so we started out class by lighting up a lightbulb with a battery and a wire.
We learned the equations P=w/t,
V=W/q, We Have An Electrical Term That Includes Units Of Work (or Energy – Remember They Are Interchangable)
P=VI=I2R=V2/R.
If you multiply power X time, we get back total energy dissipated. Dissipated - Irreversibly Lost, Dispersed, Usually As Heat
Electric power (P)
time-rate at which electric energy is expended.
SI unit: watt (W)(derived unit)
1 W = 1 J/s (1 watt = 1 joule/second)
Electric Energy(W) = Power x Time
SI Unit: joule (J)(derived unit)
Good job breaking down the class period.
great post. I especially enjoyed the bottom when you talked about what we did with our time during class.
