The eAppSuite is a collection of several helpful tools, used in the fields of electrical engeneering. They make it easier to undestand the basics of electronics. People, working on this topic, are enabled to quickly calculate electrical circuits, create own resistor networks, display formulas according to the circuit, etc. These tools are listed in the main menu. The list of tools is expandible and will be updated in further versions. One major advantage of the eAppSuite is, that many tools are included in one application. So switching between tools is very easy and quick.
