In such a situation the author asks a question – how can we calculate the effective value of voltage V? }, e-issn={2541-2486}, publisher = {Gdynia Maritime University}, keywords = { energy transfer time, effective voltage, effective current, Fryze’s concept}, doi = {https://www.doi.org/10.26408/123.03} }
