The Difference in Electrical Charge Between Two Points

Question

The difference in electrical charge between two points
A)is called the potential difference between those points.
B)is called the diffusion potential between those points.
C)is called the current,and is expressed in the units of millimoles.
D)is the same for all ions.

Accepted Answer

The difference in electrical charge between two points is called potential difference. It is measured in volts and determines the direction and strength of electrical current flow. The other options are incorrect - diffusion potential refers to the difference in ion concentration across a membrane, current is the flow of electrons, and the difference in electrical charge is not the same for all ions.
