Learners follow a methodical approach for the dc analysis of series-parallel circuits.
The Current Limiting Circuit
By Terry Bartelt
Learners examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
Hydraulic Color Code Circuit Example
In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.
The Half-Wave Rectifier
In this animated learning object, students read about the operation of a half-wave rectifier.
Learners observe animations showing how data is converted between serial and parallel flow.
Series-Parallel Practice Problems Circuit 4
By Patrick Hoppe
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

Cylinders: Basic Terminology
You'll practice defining terms relating to cylinders and identifying parts of cylinders.
I feel I'm really getting use from this site. The information is so useful and explained in easy and clear ways. I'm really thankful :)
