What is a galvanic (voltaic) cell?

• It is a cell that destroys electrons on one side and creates electrons on the other side.

• It is a cell that contains only one metal bar and one aqueous ion solution.

• It is a type of battery that drives a redox reaction when electricity is applied.

• It is a type of battery that generates an electrical current from redox reactions.
