The difference in the concentration of charged particles between two points, measured as voltage.
What is electrical current?
The flow of charged particles from one point to another.
What does it mean when something is polarized?
It has an electrical potential (a charge difference across a membrane).
What is resting membrane potential (RMP)?
The charge difference across the plasma membrane of a cell at rest.
What is the resting membrane potential (RMP) of neurons?
