1
00:00:00,280 --> 00:00:04,570
We have finished all the lessons for the 
first module. 

2
00:00:04,570 --> 00:00:08,620
That module is on the background. 
So what I'd like to do right now is do a 

3
00:00:08,620 --> 00:00:11,930
wrap up of those module, of the, those 
lessons. 

4
00:00:13,890 --> 00:00:20,100
The particular topics that we've covered 
in this module include charge, current, 

5
00:00:20,100 --> 00:00:25,640
voltage, power, resistors, sources, and 
circuits. 

6
00:00:27,840 --> 00:00:31,557
There's some important concepts and 
skills that I want you to be able to have 

7
00:00:31,557 --> 00:00:37,590
now that you've finished this module and 
done all of the homeworks for it. 

8
00:00:37,590 --> 00:00:41,466
Under the topic of Charge and Current, 
you should understand charge and current, 

9
00:00:41,466 --> 00:00:46,460
these are, understand there definitions 
and those concepts. 

10
00:00:46,460 --> 00:00:50,740
Be able to calculate the effect of one 
charge on other charges. 

11
00:00:50,740 --> 00:00:54,910
Be able to calculate current from charge 
flow in time. 

12
00:00:57,450 --> 00:01:01,135
Under the topic of voltage, understand 
how voltage is created by differences in 

13
00:01:01,135 --> 00:01:05,078
charge density. 
Understand how chemical reactions can 

14
00:01:05,078 --> 00:01:09,200
cause a voltage. 
Be able to use voltage references. 

15
00:01:11,570 --> 00:01:15,610
Power and energy. 
Be able to calculate power from energy. 

16
00:01:16,650 --> 00:01:19,469
Be able to analyze circuits using 
conservation power. 

17
00:01:20,560 --> 00:01:23,580
Be able to analyze circuits using power, 
voltage, and current. 

18
00:01:25,800 --> 00:01:27,490
You should be familiar with circuit 
diagrams. 

19
00:01:31,860 --> 00:01:32,882
Be able to identify some basic circuit 
elements. 

20
00:01:32,882 --> 00:01:33,920
Be able to identify nodes of a circuit 
diagram. 

21
00:01:35,010 --> 00:01:40,866
Be able to identify open and short 
circuits and be able to move elements of 

22
00:01:40,866 --> 00:01:48,376
a diagram around, to equivalent diagrams. 
So this covers the material that we've 

23
00:01:48,376 --> 00:01:52,862
learned in the background module. 
Our next module, will be Module 2, 

24
00:01:52,862 --> 00:01:57,330
resistive circuits and here's a friendly 
reminder. 

25
00:01:57,330 --> 00:02:01,300
Do all homework for this Module. 
Study for the quiz, and continue to visit 

26
00:02:01,300 --> 00:02:05,091
the forum. 
And this doesn't additional reminder, the 

27
00:02:05,091 --> 00:02:08,926
slides that you have seen in this module 
will be available as hard copies on, on 

28
00:02:08,926 --> 00:02:13,250
the resource section of this, for this 
module.
