Circuit Analysis For Dummies

Circuits overloaded from electric circuit analysis?

Many universities require that students pursuing a degree in
electrical or computer engineering take an Electric Circuit
Analysis course to determine who will "make the cut" and continue
in the degree program. Circuit Analysis For Dummies will
help these students to better understand electric circuit analysis
by presenting the information in an effective and straightforward
manner.

Circuit Analysis For Dummies gives you clear-cut
information about the topics covered in an electric circuit
analysis courses to help further your understanding of the subject.
By covering topics such as resistive circuits, Kirchhoff's laws,
equivalent sub-circuits, and energy storage, this book
distinguishes itself as the perfect aid for any student taking a
circuit analysis course.

• Tracks to a typical electric circuit analysis course

• Serves as an excellent supplement to your circuit analysis
  text

• Helps you score high on exam day

Whether you're pursuing a degree in electrical or computer
engineering or are simply interested in circuit analysis, you can
enhance you knowledge of the subject with Circuit Analysis For
Dummies.
