21. Unless there is proton decay-and even electron decay-one expects the universe to retain differences in electrical potential . 22. The electrical potential gradient is about-170 mV. 23. I would expect the key would be harvesting the electrical potential before it becomes an unmanageable lightning bolt. 24. This generates potential energy in the form of a pH gradient and an electrical potential across this membrane. 25. These different reactions create an electrical potential difference, just like the voltage between opposite electrodes of a battery. 26. The two pulleys have an electrical potential across them, which causes the wire to form a short circuit. 27. Signalling between cells, such as neurons for example, revolves around changes in the electrical potentials across their membranes. 28. A receptor cell converts the energy in a stimulus into a change in the electrical potential across its membrane. 29. Animals, in particular, employ sodium and potassium differentially to generate electrical potentials in animal cells, especially in nervous tissue. 30. Each time the electrical potential inside the soma reaches a certain threshold, a pulse is transmitted down the axon.
