what is the resting membrane potential?
the electrical potential difference between the nucleus and cytoplasm when a cell is at rest
electrical potential difference across the plasma membrane when a cell is at rest
the electrical potential difference across the plasma membrane when a cell is actively firing
the electrical potential difference across the cytoplasm when a cell is at rest
the electrical potential difference across the mitochondrial membrane when a cell is at rest

Explanation:

Resting membrane potential is defined as the electrical potential difference across the plasma membrane of a cell when it is at rest. This is due to the unequal distribution of ions (such as sodium, potassium) across the plasma - membrane and the selective permeability of the membrane to these ions.

Answer:

Electrical potential difference across the plasma membrane when a cell is at rest
