The difference of electrical potential between two points.
- ‘When the electrode tip is located in the vacuole, the electrical potential difference is that across two membranes, the plasma membrane and the tonoplast.’
- ‘It is defined as the energy lost or gained by an electron as it passes through a potential difference of one volt.’
- ‘This results in a decreased membrane potential, which is defined as the electrochemical potential difference of protons across the inner mitochondrial membrane.’
- ‘Application of an electric potential difference led to a parallel dichroism of this vibration.’
