**ENGIN 2210 – Circuit Analysis I**

This is an introduction to engineering circuit analysis and design. The topics include concepts of electricity and magnetism, circuit variables (units, voltage, inductance, power and energy), circuit elements (R, L, C and operational amplifiers), simple resistive circuits, circuit analysis (node-voltage, mesh-current, equivalents and superposition), transient analysis, and sinusoidal steady state (analysis and power).

## Online Circuit Simulators

**Circuit JS** – an online circuit simulator.

## Circuits Basics & Tutorials

**Electronics Tutorials** – this website provides explanations of nearly all of the topics covered in this class, with many examples.

**Glossary of Electrical Engineering Terms** – Definitions of many frequently used EE terms.

## Resistors

**Types and Applications** – not all resistors are alike. This article from *Nuts and Volts* explains how resistors are made and when to use each particular type.

## Operational Amplifiers

**How to Choose an Operational Amplifier** – this article from Nuts and Volts gives a lot of interesting information about all the specs of an op-amp, and how to choose one based on your project requirements.

## Capacitors & Inductors

**Delta-Wye Transforms for Capacitors** – this post gives the equations for Delta-Wye transforms for caps, which differ from the resistor/inductor equations.

**Bust a Cap – Exploding Capacitors** – this video from SparkFun clearly highlights the differences between ceramic, aluminum electrolytic, and tantalum electrolytic capacitors. Moral of the story: be careful not to over-volt or reverse bias your electrolytic capacitors!

**Does Inductor Winding Have You Tied in Knots? (PDF)** – this article from the July/August 2018 *Nuts and Volts* magazine explains the fundamentals of inductors.

## Filters

**Filter Design and Analysis** – this tool calculates filter frequencies based on resistor, capacitor and inductor values.

**Analog Filter Wizard** – this tool allows you to create a Bode plot and determines the filter parameters from that.

**Filter Basics (PDF)** – this article from the July/August 2018 *Nuts and Volts* magazine explains many concepts relating to filter design.
