Dablink For other words or senses of this term, see potential disambiguation . In linguistics, the Irrealis mood Potentialpotential mood The mathematic al study of potentials is known as potential theory it is the study of harmonic function s on manifold s. This mathematical formulation arises from the fact that, in physics, the scalar potential is irrotational , and thus has a vanishing Laplacian the very definition of a harmonic function. In physics , a potential may refer to the scalar potential or to the vector potential . In either case, it is a field physics field defined in space, from which many important physical properties may be derived. Leading examples are the gravitational potential and the electric potential , from which the motion of gravitating or electrically charged bodies may be obtained. Specific forces have associated potentials, including the Coulomb potential , the van der Waals potential , the Lennard Jones potential and the Yukawa potential . In electrochemistry there are Galvani potential and Volta potential . In Thermodynamics potential refers to thermodynamic potential .

Potential evaporation or potential evapotranspiration PET is defined as the amount of evaporation that would occur if a sufficient water source were available. If the evapotranspiration actual evapotranspiration is considered the net result of atmospheric demand for moisture from a surface and the ability of the surface to supply moisture, then PET is a measure of the demand side. Surface and air temperatures, insolation, and wind all affect this. A dryland is a place where annual potential evaporation exceeds annual precipitation. Estimates of potential evaporation mm C. W.

Refimprove date June 2007 Ecological health or ecological integrity or ecological damage are the symptoms of an ecosystem s pending loss of carrying capacity , its ability to perform ecological services , or a pending ecocide , due to cumulative causes such as pollution . It can also be defined in regards to farming so as to minimize the negative effects of agricultural practices. The term health is intended to evoke human environmental health concerns, which are often closely related but as a part of medicine not ecology . As with ecocide , that term assumes that ecosystems can be said to be alive see also Gaia philosophy on this issue . While the term integrity or damage seems to take no position on this, it does assume that there is a definition of integrity that can be said to apply to ecosystem s. The more political term ecological wisdom refers not only to recognition of a level of health, integrity or potential damage, but also, to a decision to do nothing more to harm that ecosystem or its dependents. An ecosystem has a good health if it is capable of self restoration after suffering external disturbances. This is termed Resilience ecology resilience .

Volta potential also called Volta potential difference , or contact potential difference , or outer potential difference , , delta psi in electrochemistry , is the electric potential difference between two points 1 and 2 in the vacuum point 1 close to the surface of metal M sub 1 sub point 2 close to the surface of metal M sub 2 sub or electrolyte where M sub 1 sub and M sub 2 sub are two uncharged metals brought into contact. ref http www.iupac.org goldbook C01293.pdf IUPAC Gold Book, definition of contact Volta potential difference. ref The Volta potential is named after Alessandro Volta . Volta potential between two metals When two metals are electrically isolated from each other, an arbitrary potential difference may exist between them. However, when two different metals are brought into contact, electrons will flow from the metal with a lower work function to the metal with the higher work function until the electrochemical potential of the electrons in the bulk of both phases are equal. The actual numbers of electrons that passes between the two phases is small, and the occupancy of the Fermi level s is practically unaffected. Measurement of Volta potential The Volta potential difference is measurable. It is related to the capacitance of an electrostatic capacitor , the two sides of which are made of the two metals for which the Volta potential difference is measured and the electrical charge used to load the capacitor. The Volta potential difference between a metal and an electrolyte can be measured in a similar fashion. ref V.S.

Full expression of the biotic potential of an organism is restricted by environmental resistance , any condition that inhibits the increase in number of the population. It is generally only reached when environmental conditions are very favorable. A species reaching its biotic potential would exhibit exponential population growth and be said to have a high fertility , that is, how many offspring are produced per mother.

multiple issues confusing June 2010 unreferenced June 2010 The endocochlear potential is the main resting potential in the cochlea . It is a positive direct current of 80mV which can be recorded from the endolymph with electrodes. When a sound is presented, the endocochlear potential changes either positive or negative in the endolymph , depending on the stimulus. The change in the potential is called the summating potential . With the movement of the basilar membrane , a shear force is created and a small potential is generated due to a difference in potential between the endolymph scala media 80 mV and the perilymph vestibular and tympanic ducts 70 mV . An acoustic stimulus produces a simultaneous change in conductance at the membrane of the receptor cell. Because there is a steep gradient 150 mV, changes in membrane conductance are accompanied by rapid influx and efflux of ions which in turn produce the receptor potential. This is known as the Battery Hypothesis. The receptor potential for each hair cell causes a release of neurotransmitter at its basal pole, which elicits excitation of the afferent nerve fibres.

Unreferenced date December 2006 A synaptic potential also known as a postsynaptic potential is an alteration in the membrane potential of a cell resulting from activation of a chemical synapse synaptic input . All animal cells maintain a voltage difference between the intracellular and extracellular regions, holding the intracellular region at a negative voltage that in a baseline state is usually in the range 30 to 70 millivolts. Synaptic inputs from neuron s can alter this voltage difference. If the intracellular voltage rises, the signal is called an excitatory postsynaptic potential EPSP if it falls the signal is called an inhibitory postsynaptic potential IPSP . If the cell is electrically excitable, a sufficiently large EPSP may cause it to generate an action potential . Category Cell biology Neuroscience stub Medicine stub ... more details

An example of this is in a taste bud , where taste is converted into an electrical signal sent to the brain. When stimulated, the taste bud triggers the release of neurotransmitter through exocytosis of synaptic vesicles from the presynaptic membrane.

Actual recordings of action potentials are often distorted compared to the schematic view because of variations in electrophysiology electrophysiological techniques used to make the recording. The threshold potential is the membrane potential to which a membrane must be depolarization depolarized to initiate an action potential .
