For today's class, we did a lab on Parallel and Series Circuit. The lab can be found on the green text book page 479. The purpose of doing this particular lab is to be able to construct series, parallel and combination circuits. After doing the lab, we were given the rest of the period to either work on the two worksheets that were given the day before or work on the exam review.
And that was everything for today.
The next scribe is ROJUANE!

For today's class, we started off by watching a movie about Electric Current. We were to write 5 to 7 points about the movie. We then went over the questions from the green book that was assigned last Friday. Here are the answers:

1. a.) 25 ohms
b.) 2 A
c.) 40 V and 10 V
d.) 80 W and 20 W

2. 2 Watts each

3. a.) 60 ohms
b.) .2 A

4. a.) 60 ohms
b.) 6 V

5. a.) 1.5 A
b.) 30 ohms

13. 6V

14. a.) 8.9 ohms
b.) 4.5 A
c.) 2.5 A

We were also given a hand out about Series and Parallel Elements. It gave us all the information to be able to calculate any individual voltages and currents. Two other worksheets were also handed out, Chapter 35: Electric Circuits and 14.8 Power in Electric Circuits to give us some practice with Series and Parallel Elements. And that was everything for today.
DONT FORGET ABOUT THE TEST ON JANUARY 20TH.

And the next scribe is...

Jan. 9, 2009 Physics

Friday's class consisted of a closer look at series and parallel circuits. Some examples of calculations include:

-Potential difference is found in the source of the circuit. Can be calculated, V = IR. In a series circuit, individual potential drops add up to the total potential drop. In a parallel circuit, it is constant across the whole circuit.

-In a series circuit, current is constant throughout the entire circuit. In parallel, individual currents are added to equal the total current.

-Resistance in a series circuit can be found by simply adding up all resistances within the circuit. However, in parallel, you must add the reciprocal of each resistor value and solve using the inverse of the total of all the resistance reciprocals.

-Power can be calculated, P = IV, in a series circuit. In parallel, it must be calculated using the formula P = V²/R.

We were also assigned questions 1-5, 13, and 14 on page 488 in the green textbook. The exam review has been handed out so start studying ;)

Christine scribes next.

Thursday's Blog

Today in class we got a lot of work sheets to go crazy over. We also did some corrected so here we go..

We went over the Chapter 23 Study Guide we got the previous day:

Then we got 2 new worksheets to work on: 31 Circuit Symbols and 32 Circuits and Circuit Diagrams:

Afterward we got another worksheet: Simple Circuits. We went over question 1:

Annd that's it! Question 2 on that Simple Circuits worksheet is due for tomorrow.
The next scribe will be Dana.

Wednesday's Blog

HELLOOOOOO. This is the day where Ms. K wasn't here and we had a sub.

We went over the: Resistivity Problems we got on monday with her. Here are the answers:

After that, we got the chapter 23 study guide that was due for thursday.
That's about all we did in class that day!

Last First Day Back for Winter DMCI

Today in class we got back our test that we did before the break some did excellent and some didn't do to well... We also corrected the test as well.

The Next thing that we got were some sheet that we read with the whole class it was about Conventional Currents. We also got another sheet on Conventional Currents again.

After that we got handouts and one of the handouts will be due tomorrow. OH no on Wednesday because we only have half day tomorrow.

Study Hard and keep doing your work.
Rguy out

ps. ERiC you still are the scribe
