11. The concentration of sodium ions is intimately related to the electrical potential across a membrane. 12. When the instabilities developed, areas of enormous electrical potential developed, rapidly accelerating protons in the area. 13. A device called an electromyograph measures the electrical potential of muscle cells to monitor muscle movement. 14. Zeikus and Park are not the only researchers exploring the electrical potential of sugar-fed biofuel cells. 15. The nerve pathways from the eyes and ears carry the elicited electrical potentials into the thalamus. 16. The electrical potential energy sustained by magnetic capacitivity varies with the frequency of oscillations in magnetic fields. 17. The mechanisms for the proliferation and sustained electrical potentials were affected by the fast axonal transport system. 18. In the valley, the river has a huge hydro electrical potential , but none is used so far. 19. This brings all the bonded items to the same electrical potential as a protection from electrical shock. 20. Upon viewing it again, the phenomenon I am having difficulty in understanding is " electrical potential ".
