  In our days, the necessity of laboratory apparatus accustoming by building up
specific software objects for studying the virtual evolution of physical
phenomena is a major request. In this respect, the aim of the present paper is
to present a developed set of electricity interactive simulation computer
applica-tions. By following an Object Oriented Programming technology, the
necessary software objects are described. Finally, specific examples are
extensively presented as well as some screen-shots of the applications
interface.
