Variation of Electrical Resistivity and Charge Passed in High-Performance Concrete

Autor: Quang Tran, Pratanu Ghosh

Publikováno v: Materials; Volume 15; Issue 19; Pages: 6694

This study investigated the variation of bulk resistivity (BR) and charge passed for various high-performance concrete (HPC) mixtures based on significant factors (i.e., geometric size, operation frequency, and mixture constituents and proportions) u

Optimalizace užitných vlastností olověných akumulátorů

Autor: Lábus, Radek

This thesis focuses on the limitations of degradation mechanisms of Lead-Acid batteries, which significantly contributes unequal distribution of current (and therefore internal resistance, charge passed and power loss) on the surface of the electrode
