31. It has been proposed that while the pH gradient has been reversed, the transmembrane electrical potential is greatly increased. 32. "In short the anode current is controlled by the electrical potential ( voltage ) of the first grid ." 33. Electrooculography ( EOG ) measures the difference in electrical potential between the front and the back of the eye. 34. The electron energy is set by the electrical potential difference ( voltage ) between the sample and the tip. 35. The latter is also just a definition; resistance is defined as the amount of electrical potential drop per unit current. 36. Electro propels himself along magnetic lines of force in objects that have great electrical potential , such as high-tension electrical lines. 37. If the train were centered with the coils, the electrical potential would be balanced and no currents would be induced. 38. A semi-conducting glaze may be used to assist in equalizing the electrical potential gradient along the length of the bushing. 39. I did some searching without much success; found this little experiment, and a claim that plants contain high electrical potential . 40. When an electrochemical signal stimulates a neuron it causes changes in the electrical potential across the neuron s plasma membrane.
