Termkionico document is only for private use for research and teaching activities. The studied electrical parameters were the equivalent series resistance obtained by the method of the instantaneous value of the voltage drop ESR Instwhere the acronym ESR has the meaning Equivalent Series Resistance, the equivalent parallel resistance EPR Dep obtained by the method of dependent value, where the acronym EPR has the meaning Equivalent Parallel Resistance, and the capacitance C DC obtained by the method of direct current.
The text present termoiinico the changes that the MgB 2 discovery brings to research and applications. In this article the discovery of the superconductivity at39K in MgB 2 is discussed in a didactic and conceptual way.

The data given by microstructural images of the homogeneity and porosity values correlated by the chemical composition and possible contaminations present in the electrodes. This paper aims to report information on electrical and microstructural characteristics of electrodes applied at devices that store energy, specifically supercapacitors made of activated carbon electrodes.
Made experiments it was concluded that the parameter further deterioration suffered with the increase of thermal energy is EPR Depthen C DCwhich in fact little changed and ESR Instin which the change in the measurement error was are noticeable. These parameters were chosen because of the impact they have on lifetime, the storage capacity of electric charge, the speed of loading and unloading, the loss thermionic effect on the charge and discharge processes and loss of stored charge due to self-discharge in supercapacitors.
Introduction to the superconductivity, its applications and the mini-revolution provoked by the rediscovered of the MgB 2: To point out its importance the history of the superconductors is discribed shortly, from its discovery in in Hg up to nowadays. The main inherent characteristics to the superconductor state are pointed out and some of its applications are indicated and represented in illustrations.
