The Structure of the Cell Membrane Resting Membrane Potential

Electrical potential
● Electric potential: work required by an
electric field to move electric charges
(expressed in volts and can be measured
by a voltmeter).
● Electrical gradients:
The sum of the “+” and “-” are not the same
at the different points in space.
An electric field creates a force that can
move the charged particles (the work of the
electric field) → moving charged particles =
electric current.
