A network, in the context of electrical engineering and electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, all network components. There are many techniques for calculating these values. However, for the most part, the techniques assume linear components.
Except where stated, the methods described in this article are applicable only to linear network analysis.
This problem seems so simple, but I CANNOT get the right answer.Here is the work I've done so far:
I've also attached the work, but if anyone wants to check the links before it gets approved, please be my guest.
The books says that the correct answer is:
V0 = 2.24 at an angle of -153.43

I need to analyze a Wien-Bridge Oscillator for stability. Over the last day or so, I've taught myself to understand different op-amp circuits where I have well-defined V(in) and V(out).
For the oscillator circuit though, there really is no such thing as V(in). There's a V(out) which evolves...
Since Greg recently started allowing Maple worksheets as attachments and since this lonely little forum gets hardly any traffic, I'm going to start using it as an incubator for the development of tutorials for use at PF.
I've attached a Maple worksheet (done in Maple 9.5) that shows how to do...
Sorry, no picture my bad.
Here is the circuit, everything is in PARALLEL,
First its a 1mA source, then its a switch, then its a resistor of 10k-ohm then its a capacitor 1uF. Sorta like below:

Hi, I'm wondering if I made a mistake in getting the Kirchhoff equations to find all the currents.
Here's what I got:
Loop 1:
10.0I_1 + 20.0I_2 + 30.0 I_4 = 15.0 V
Loop 2:
40.0I_3 + 30.0 I_4 = 15.0 V
Loop 3:
20.0I_2 + 30.0 I_4 = 10.0 V
Current Law:
I_2 + I_3 - I_4 = 0 A...
I'm confused with something really basic, and it is bothering me. I'm not sure if there is a way to draw circuits with LaTeX on this forum (or even how to do it if there is), so please excuse the ASCII art. (If there is a way to draw them, I'll be more than happy to learn. Anyways...

A MP3 player is powered by a 6V battery pack that can supply 600mA-hr of current. If the MP3 player draws 30 mA of current, how long will the battery last before it needs recharging? and What is the power used by the MP3 player?
if any1 can help i'd appreciate it
PROBLEM:the current at the terminals of a certain current source is measured with an ammeter having an internal resistance R_i=10 ohms and is found to be 11.988 mA ;adding a 1.2 kilo -ohms resistance between the source terminals causes the ammeter reading to drop to 11.889 mA.Find i_s and R_s...
Hi Guys,
I'm a first year Electrical Engineering student and we're just covering the basics of circuit analysis. Currently we are going over Nodal analysis.
I'm having some trouble correctly identifying the currents that are entering and leaving a node in a circuit. I can get most simple...
Hey all, I'm looking for good books or guides on basic circuit analysis techniques.
Is there a book that is known as a "staple" in teaching circuit analysis - like, for example, the Halliday & Resnick book for physics?
Thanks.
hey guys
i posted this in the electrical engineering section
but realized this may have been a better place to
post since i am studying this in university :-)

A diagram of the circuit can be seen here

ok the question I have is why is the voltage between the 220 olm resistor and the 330 olm resistor 0 V.
All resistors in the image are in series so Is=I1=I2=I3
Is = 10/1020 (v/olm) = .0098 or 9.8 mA
V(subscript220)= 220*9.8 mA = 2.157 V (this is the voltage between the DC source and...
Va = -10 V, Vb = 10 V, I (through R2)= 2mA
R4 = 2*R2 and R3 = 4*R5
Find the resistances.
Now, we have just started talking about Thevinin' s method and not yet discused Norton' s method. We have also finished Mesh current, Nodal and Branch methods for circuit analysis.

Need a good "Introduction to Circuit Analysis book"
I am studying to be an EE and will be taking my first circuits, and computer engineering classes this fall and would would really like to get a head start on the material. The textbook for the circuits course is "Basic Engineering Circuit...
:confused: I'm a beginner so be gentle.
Trying to figure out currents in the attached image of a ciircuit I've been pulling hair out over.
No need to fully analyze it, simply trying to determine what current (AC or DC) is flowing through each component.
More importantly, how on Earth...
I was working on a project work on Electrical Circuit Analysis with c++(bgi mode) and now I'm having problems with the mouse drivers and the connecting cables .
Would anyone help me with this?
