Under resting conditions, the inside of a cell is negatively charged compared to the outside due to the distribution of ions across the membrane. When an action potential is generated, the inside of the cell briefly becomes positive relative to the outside due to the influx of sodium ions.

Under Conditions of Resting Membrane Potential, the Inside of the Cell
