00:00:00,012 --> 00:00:07,692
Hello again, so we are now at the point 
where we're ready to wrap up module 

2
00:00:07,692 --> 00:00:12,874
number 2. 
So, far in this module on resistive 

3
00:00:12,874 --> 00:00:17,164
circuits, we've covered these topic, 
Resistors Ohm's law, Kirchoff's Laws, 

4
00:00:17,164 --> 00:00:23,114
series and parallel resistors. 
Superposition, Circuit equations, Maximum 

5
00:00:23,114 --> 00:00:27,962
power, Wye Delta configurations, and 
applications and sensors. 

6
00:00:27,962 --> 00:00:33,402
There are a number of very specific 
important skills and, and concepts that I 

7
00:00:33,402 --> 00:00:38,556
want you to know and have. 
And these are going to be important for 

8
00:00:38,556 --> 00:00:41,912
the quiz. 
So, I'm going to go through these as to 

9
00:00:41,912 --> 00:00:46,700
what the, your expectations are on, on 
these various topics. 

10
00:00:46,700 --> 00:00:50,143
And study this for the quiz. 
On resistance, you should be able to 

11
00:00:50,143 --> 00:00:54,096
reduce resistive networks to single 
equivalent resistance using parallel and 

12
00:00:54,096 --> 00:00:58,504
series connections. 
You should be able to apply Kirchoff's 

13
00:00:58,504 --> 00:01:01,362
laws. 
Understand them, and be able to apply 

14
00:01:01,362 --> 00:01:06,598
them to circuits to obtain equations. 
Be able to compute voltages and currents 

15
00:01:06,598 --> 00:01:09,762
from the voltage divider law, and the 
current divider laws. 

16
00:01:09,762 --> 00:01:14,690
Understand superposition and its 
application in circuits to find specific 

17
00:01:14,690 --> 00:01:19,270
voltages and currents. 
And remember superposition is used when 

18
00:01:19,270 --> 00:01:26,031
you got multiple sources. 
We looked at physical circuits and 

19
00:01:26,031 --> 00:01:29,408
components. 
Given a color chart, be able to identify 

20
00:01:29,408 --> 00:01:33,090
the physical resistor values and 
tolerances. 

21
00:01:33,090 --> 00:01:37,800
Understand the purpose of a protoboard or 
breadboard and its basic operation. 

22
00:01:37,800 --> 00:01:41,639
Understand how current can be measure in 
a circuit using the voltage divider law. 

23
00:01:43,490 --> 00:01:46,845
In superposition given a circuit with 
multiple sources be able to use the 

24
00:01:46,845 --> 00:01:51,300
Superposition Principle to solve for 
circuit voltages and currents. 

25
00:01:53,390 --> 00:01:56,285
We spend a lot of time looking for 
systematic solution methods. 

26
00:01:56,285 --> 00:02:02,489
We did mesh analysis, node analysis, and 
Thevenin and Norton equivalent circuits. 

27
00:02:03,530 --> 00:02:05,710
When we talked about when to use one 
versus another. 

28
00:02:06,730 --> 00:02:10,874
Have a basic understanding of those. 
And then be able to solve specific 

29
00:02:10,874 --> 00:02:15,438
voltages and currents in a given circuit. 
Now I'm not going to require you to solve 

30
00:02:15,438 --> 00:02:18,619
a given circuit using any one of these 
methods. 

31
00:02:18,619 --> 00:02:21,260
You can use which ever one that you're 
comfortable with. 

32
00:02:21,260 --> 00:02:23,990
And many students just latch onto one, 
and that's the one that they're going to 

33
00:02:23,990 --> 00:02:26,196
use. 
But we give you the background in all of 

34
00:02:26,196 --> 00:02:28,890
these. 
And there's extra problems in these. 

35
00:02:28,890 --> 00:02:30,599
So, make sure that you're comfortable 
working these. 

36
00:02:33,160 --> 00:02:36,260
And the Maximum Power Transfer, be able 
to compute the load resistance the 

37
00:02:36,260 --> 00:02:39,060
maximizes the power delivered to that 
load. 

38
00:02:41,380 --> 00:02:45,010
On Wye and Delta circuits, know the 
transformation, and understand that these 

39
00:02:45,010 --> 00:02:48,750
configurations may be used in different 
applications, such as 3 phase circuits, 

40
00:02:48,750 --> 00:02:55,408
such as 3 phase motors in particular. 
We spend a lot of time looking at 

41
00:02:55,408 --> 00:02:59,755
applications, resistors and sensors. 
Know examples of resistors that vary with 

42
00:02:59,755 --> 00:03:03,625
physical quantities. 
Understand how a potentiometer is used to 

43
00:03:03,625 --> 00:03:07,589
measure position or angle. 
Know when a Wheatstone Bridge is used in 

44
00:03:07,589 --> 00:03:10,908
a practical application. 
Be able to write equations for a 

45
00:03:10,908 --> 00:03:14,920
Wheatstone Bridge. 
So, looking back at the concept map, 

46
00:03:14,920 --> 00:03:17,830
we've completed modules one and modules 
two. 

47
00:03:17,830 --> 00:03:21,145
The next module that we will cover is 
module three on reactive circuits, and we 

48
00:03:21,145 --> 00:03:24,256
will build upon the information, the 
knowledge that we gained from these 

49
00:03:24,256 --> 00:03:30,222
previous modules. 
As a reminder, please do all homework for 

50
00:03:30,222 --> 00:03:34,024
this module. 
Study for the quiz and make sure you go 

51
00:03:34,024 --> 00:03:37,608
back and look at some of the extra 
problems that we put in the, in this 

52
00:03:37,608 --> 00:03:43,750
section, the extra work problems on 
solving for, for circuits. 

53
00:03:43,750 --> 00:03:47,442
continue to visit the forum. 
Ask questions and please try to answer 

54
00:03:47,442 --> 00:03:50,120
the questions. 
Good luck on the quiz.
