Electric current and resistors
Electric energy tutorial energy sources can basically be broken into renewable and depletable sources, which ultimately originate from space and terrestrial sources, respectively. The space sources include solar and lunar origins where the latter gravitational energy results in tidal flows. The sun provides directly useable energy as well as indirectly providing hydro, wind, ocean (thermal & current), and even biomass through photosynthesis
