James A. Svoboda - ECE Department, Clarkson University has created numerous interactive examples throughout the textbook - Introduction to Electric Circuits. Interactive Examples made of Java Applets.

Interactive Examples and Exercises - Jim Svoboda

The Interactive Exercise shown here considers a similar, but different, circuit. Like the Interactive Example, the Interactive Exercise poses a problem, then accepts and checks the user's answer. Student learning is further supported by extensive help, in the form of worked example problems, available from within the Interactive Exercise using the “Worked Example” button.

Circuit Design Lab

The Circuit Design Lab consists of several Java applets, each providing an opportunity to experiment with the design of a particular circuit:

Variations of this problem are obtained using the “New Problem” button. We can peek at the answer using the “Show Answer” button. The Interactive Example and Exercises provide hundreds of addition practice problems with countless variations, all with answers that are checked immediately by the computer.

### Periodic Table and other Calculators

Periodic table of the elements contains the basic data about the elements in five languages.

Periodic Table and other Calculators

Chemistry Assistant - scientific calculator for fast calculations of molecular weight, quadratic equations, chemicals for preparations of solutions and statistic analysis.

EniG. Chemistry Assistant is an expression calculator for fast calculation of molecular weight of compounds by simple entry of chemical formula, and replaces the element symbols with their atomic weight. The program translates texts with chemical element symbols or without them into a mathematical expression and calculates them. The program includes functions for statistical analysis, solving the quadratic equation, physical constants, and prepare solution calculator

Periodic Table of the Elements - shows the change of the standard state of elements with the change of temeperature on 7 languages.

### Analog Op-Amp Interactive Tutors

I have made some Web Widgets, these are analog opamp tutors. Interactive Tutorial with Simulated Meters and Potentiometers, demonstrating how Operational Amplifier functions in different configurations.

The mV buttons are special, the variation picks up speed if you let the mouse pointer remain on the button. This is Ramp-up and Ramp-down. This enables you to set it faster with just two buttons.Finally you have a
