WebJan 16, 2024 · When a thermoelectric material is exposed to a temperature gradient — for example, one end is heated, while the other is cooled — electrons in that material start to flow from the hot end to the … In physics, chemistry and biology, a potential gradient is the local rate of change of the potential with respect to displacement, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to some form of flux. See more One dimension The simplest definition for a potential gradient F in one dimension is the following: where ϕ(x) is some … See more In biology, a potential gradient is the net difference in electric charge across a cell membrane. See more Since gradients in potentials correspond to physical fields, it makes no difference if a constant is added on (it is erased by the gradient operator ∇ which includes partial differentiation). This means there is no way to tell what the "absolute value" of the potential "is" – the … See more • Tensors in curvilinear coordinates See more Newtonian gravitation In the case of the gravitational field g, which can be shown to be conservative, it is equal to the gradient in gravitational potential See more In an electrochemical half-cell, at the interface between the electrolyte (an ionic solution) and the metal electrode, the standard electric potential difference is: where R = gas constant, T = temperature of solution, z = See more Field equations, such as Gauss's laws for electricity, for magnetism, and for gravity, can be written in the form: $${\displaystyle \nabla \cdot \mathbf {F} =X\rho }$$ See more
