Equilibrium potential is referring to the equilibrium (or balance) established between the forces of diffusion and electrical forces specific to each ion. For example, the equilibrium potential for Potassium, K+, in a cell with a semi permeable membrane is -80mV or Ek+=80mV. The membrane potential, on the other hand, refers to the voltage across the membrane at anytime and takes into account a range of equilibrium potentials such as Potassium, Sodium etc.

What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
The electrical charge resulting from the difference between the positive and negative ions outside and?
The electrical charge resulting from the difference between positive and negative ions outside a cell is called the membrane potential. This potential difference is essential for processes like nerve impulses and muscle contractions. The cell membrane selectively allows ions to move in and out, creating an imbalance that generates the membrane potential.
A charge difference between the interior of the neuron axon and the exterior exists when the neuron is?
When the neuron is at rest, a charge difference known as the resting membrane potential exists between the interior and exterior of the axon. This potential is maintained by the unequal distribution of ions across the cell membrane, with more negative ions inside the cell compared to the outside.
Does a battery represent a system at equilibrium?
No, a battery does not represent a system at equilibrium. A battery operates by creating a potential difference between its terminals through chemical reactions, which is a non-equilibrium process as it involves the flow of electrons from one terminal to the other.
Difference in a charge between two electrodes in a cell causes a ----between electrodes?

What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
The electrical charge resulting from the difference between the positive and negative ions outside and?
The electrical charge resulting from the difference between positive and negative ions outside a cell is called the membrane potential. This potential difference is essential for processes like nerve impulses and muscle contractions. The cell membrane selectively allows ions to move in and out, creating an imbalance that generates the membrane potential.
What is the relationship between membrane potential and resting potential in a cell?
The resting potential of a cell is the membrane potential when the cell is at rest, typically around -70 millivolts. Membrane potential refers to the difference in electrical charge across the cell membrane. Resting potential is a type of membrane potential that is maintained when the cell is not actively sending signals.
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What is membrain potential?
Membrane potential refers to the difference in electrical charge between the inside and outside of a cell membrane. This difference is usually negative inside the cell compared to the outside, due to the distribution of ions across the membrane. Membrane potential is essential for many cellular processes, including nerve impulse propagation and muscle contraction.
What is resting potential?
A rest potential is the potential difference between two sides of the membrane of nerve cells when the cell is not conducting an impulse. =)
What is the difference in electrical charge between two regions on a nerve?
There is a slight difference in electrical charge between the inside and outside of a nerve cell membrane, known as the resting membrane potential. This potential is typically around -70 millivolts, with the inside of the cell more negative compared to the outside. This difference in charge is essential for the nerve cell to transmit electrical signals.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
This electrical charge is called the resting membrane potential. It is generated by the unequal distribution of ions such as sodium, potassium, chloride, and calcium inside and outside the cell. The resting membrane potential plays a crucial role in cell communication and proper functioning of the nervous system.
