Hello again, so we are now at the point where we're ready to wrap up module
number 2. So, far in this module on resistive
circuits, we've covered these topic, Resistors Ohm's law, Kirchoff's Laws,
series and parallel resistors. Superposition, Circuit equations, Maximum
power, Wye Delta configurations, and applications and sensors.
There are a number of very specific important skills and, and concepts that I
want you to know and have. And these are going to be important for
the quiz. So, I'm going to go through these as to
what the, your expectations are on, on these various topics.
And study this for the quiz. On resistance, you should be able to
reduce resistive networks to single equivalent resistance using parallel and
series connections. You should be able to apply Kirchoff's
laws. Understand them, and be able to apply
them to circuits to obtain equations. Be able to compute voltages and currents
from the voltage divider law, and the current divider laws.
Understand superposition and its application in circuits to find specific
voltages and currents. And remember superposition is used when
you got multiple sources. We looked at physical circuits and
components. Given a color chart, be able to identify
the physical resistor values and tolerances.
Understand the purpose of a protoboard or breadboard and its basic operation.
Understand how current can be measure in a circuit using the voltage divider law.
In superposition given a circuit with multiple sources be able to use the
Superposition Principle to solve for circuit voltages and currents.
We spend a lot of time looking for systematic solution methods.
We did mesh analysis, node analysis, and Thevenin and Norton equivalent circuits.
When we talked about when to use one versus another.
Have a basic understanding of those. And then be able to solve specific
voltages and currents in a given circuit. Now I'm not going to require you to solve
a given circuit using any one of these methods.
You can use which ever one that you're comfortable with.
And many students just latch onto one, and that's the one that they're going to
use. But we give you the background in all of
these. And there's extra problems in these.
So, make sure that you're comfortable working these.
And the Maximum Power Transfer, be able to compute the load resistance the
maximizes the power delivered to that load.
On Wye and Delta circuits, know the transformation, and understand that these
configurations may be used in different applications, such as 3 phase circuits,
such as 3 phase motors in particular. We spend a lot of time looking at
applications, resistors and sensors. Know examples of resistors that vary with
physical quantities. Understand how a potentiometer is used to
measure position or angle. Know when a Wheatstone Bridge is used in
a practical application. Be able to write equations for a
Wheatstone Bridge. So, looking back at the concept map,
we've completed modules one and modules two.
The next module that we will cover is module three on reactive circuits, and we
will build upon the information, the knowledge that we gained from these
previous modules. As a reminder, please do all homework for
this module. Study for the quiz and make sure you go
back and look at some of the extra problems that we put in the, in this
section, the extra work problems on solving for, for circuits.
continue to visit the forum. Ask questions and please try to answer
the questions. Good luck on the quiz.
