Example Review

DC Circuits
http://www.physics.uoguelph.ca/tutorials/ohm/Q.ohm.html

I chose this website because it had content that looked like it closely matched what we were learning in class.

Educational: This site has a lot of useful information such as Ohm’s Law and basic schematic diagrams but it doesn’t take the time to make the concepts clear for the reader (important if you’re new to electronics like me). I would have appreciated more applied explanations of the topics before just leaping in like they did.

Organization: A side navigation bar would be greatly beneficial to this website. I found it troublesome to have to go to the bottom of every page to choose my destination. The provided links do the job though (i.e. Back, Next, Return to Main…)

Suitability: This site is fairly suitable for our class as it touches on similar electronics-related topics, however I would not recommend it as a resource simply because there is much clearer, well laid-out information available on other sites on the web.

Aesthetics: This site has a very uninteresting look to it. It makes it easy to read, but does not grab your attention or interest.

Ratings:

Educational: **
Organization: ***
Suitability: ***
Aesthetics: *

Overall: ***

Marking Method

10% will be deducted if there is no title.

Up to 10% will be deducted for each grammar or spelling error that has to be fixed.

Up to 10% will be deducted for each category of the rating system that is not mentioned in the review (which is impossible to do if you follow the guidelines!).

20% will be deducted if there is no rating.

Things Not To Say in Your Review

“This website contains a large amount of information on it.” (Be specific about content.)
“All I can say is Wow. After finding many sites that didn’t do jack for me I found a great site. I found it hard to believe that this site is hosted on a Geocities account.” (A lot of words without saying anything specific about the site.)
“This website is jam packed full of goodies.” (What kind of goodies? Be specific about content.)
“This site is very nice.” (Says nothing about the site.)

Five Steps in Solving Ohm’s Law Problems

    1. Identify the Variables
    2. Write Down the Formula
    3. Substitute the Variables
    4. Solve
    5. Don’t Forget Units!

    Example Problem

    Determine the resistance of a lamp drawing 250 mA at 200 V.

    Example Solution

     I  = 250 mA = 0.25 A
    V  = 200 V
    R  = ?
    R  = V / I
     = 200 / 0.25
     = 800 Ω
