Electronics and Electricity

Small circuit simulator to learn Ohm's law (Java applet, Università di Messina).

Changing voltage and resistance you get the current magnitude.

Small circuit simulator lo learn series resistance rule (Java applet, Università di Messina)

You can modify the circuit configuration and look to voltage and current.

Small circuit simulator to  learn shunt resistance rule (Java applet, Università di Messina)

You can modify the circuit configuration and look to voltage and current.

Small circuit simulator showing Joule effect (Java applet, Università di Messina)

Changing resistance value you can see the change in temperature of the resistor, due to dissipated power.

Small circuit simulator to show the operation of current generators (Java applet, Università di Messina)

Shows the operation of a DC (dynamo) and of a AC generator.

Small simulator showing induced currents (Java applet, Università di Messina)

It show how a magnetic flux variation generates a current in a coil.

Small simulator showing the Kirchhoff's law (Java applet, Università di Messina)

You can check the Kirchhoff law by changing resistance and voltage values.

Small simulator showing the operatin of a DC current motor (Java applet, Università di Messina)

An animation showing that a Dc current motor is nothing but the reverse of a DC generator.

MSmall simulator of a charge/disharge of a capacitor (Java applet, Università di Messina)

You can switch from charge to discharge, looking at the voltage plot..

A complete "design capture" and simulation suite based on Spice: MicroCap.

This is a demo version (Evaluation Version) of a complete and up-to-date commercial suite. demop version has some limitation (some functionality is inhibited, and the number of nodes in the circuit is limited). It has neverthless no expiration time, and limitations are compatible with learning purposes. User interface is firendly, and simulation (transient, Ac, DC) made very easy. A previous knowledge of circuit theory is of course required.

A full Open Source (GNU) suite for design capture, PCB routing and generation, SPICE simulation, and so on: gEDA. For various Linux flavors, Unix and Mac OsX (via Fink).

As every Open Source project, it is a complete ad unlimited version, for those who own a MacIntosh or have installed Linux on thier own PC-like computer. The gEDA project page is here.development windows version is here (look for  win32), although dating from 2003..
