Electric circuit

Good afternoon my scattered classmates. This is Wahida posting.

Let's begin from friday, May, 28, 2010:

We had a sub- Ms. Woo (I believe). With her help we corrected the chapter 23 Study Guide. If you need the answers I will be more than happy to lend to mine.
Next we corrected Chapter 35: Electric Circuits- COMPOUND CIRCUITS. The answers are as follows:
1. 1/5 +1/5 =2/5
=5/2
=2.5 ohms
2. 1/8 + 1/8 =2/8
=8/2
=4ohms
3a. 1 ohm+1 ohm=2 ohms 1/2+1/2=1

3 b. 1 ohm

4b.
power current voltage
4W 2A 2V
8W 2A 4V

4c.
power current voltage
6W 1A 6V
12W 2A 6V

4d.
power current voltage
4.5W 1.5A 3V
$.5W 1.5A 3V
9W 3A 3V

Next we were assigned Question from the Green textbook. They are as follows:
Do #9 on applying concepts, pg 487, also on pg. 488-489 questions 13,14,16,17.

Now to the present: Ms. Kozoriz was back!! yay
Naturally, we went over the questions assigned on Friday. so here are the answers:
9. a. series b. series c. parallel d. series e. parallel f. series g. series h. parallel i. parallel

13. 6V

14a. 8.89 ohms b. 4.5A c. 2.5A
16. a. 2A b. 3A c. 15A d. yes it will.
By the way question 17 is or was to be handed in today. you may still be able to do if you haven't already.
Please leave me a comment at the bottom of this post if I've got any answers incorrect. thanks!
Also we got the answers to exam review qjuestions
Also went through a Transparency Worksheet today.
Also we got a Study Guide Booklet and a sheet- SERIES AND PARALLEL ELEMENTS.
Also we were given a link on a piece of paper, which suppose to help us with next week Friday's test.
here is the link if you don't have it: http://higheredbcs.wiley.com/legacy/college/cutnell/0471151831/concepts/index.htm?newwindow=true
