Voltage Clamp Cell. This clamps the cell membrane at a desired constant voltage allowing the voltage clamp to record what currents are delivered. Stepwise changes in voltage produced by this technique cause channels to interconvert between different states and these transitions are monitored as changes in membrane current.

As sodium enters the cell the voltage clamp equipment injects equal but opposite current into the cell to keep the membrane potential stable. Under voltage clamp conditions voltage gated ion channels open and close as normal but the voltage clamp apparatus compensates for the changes in the ion current to maintain a constant membrane potential. The voltage clamp is a classic electrophysiological technique to measure ion currents across the cell membrane.
The voltage clamp is a technique used to control the voltage across the membrane of a small or isopotential area of a nerve cell by an electronic feedback circuit.

Under voltage clamp conditions voltage gated ion channels open and close as normal but the voltage clamp apparatus compensates for the changes in the ion current to maintain a constant membrane potential. A basic voltage clamp will iteratively measure the membrane potential and then change the membrane potential to a desired value by adding the necessary current.
