Volta River Volta River The Volta River is the main river system in the West African country of Ghana. It flows into Ghana from Bobo-Dioulasso highlands of Burkina Faso. The main part of the river are the Black Volta, the White Volta, and the Red Volta. In the northwest, the Black Volta forms the international boundaries between the Ivory Coast, Ghana, and Burkina Faso. The Volta flows southward along Akwapim-Togoland highlands, and it empties into the Atlantic Ocean at the Gulf of Guinea at Ada. It has a smaller tributary river, the Oti, which enters Ghana from Togo in the east. The
Volta potential Volta potential The Volta potential (also called Volta potential difference, contact potential difference, outer potential difference, Δψ, or "delta psi") in electrochemistry, is the electrostatic potential difference between two metals (or one metal and one electrolyte) that are in contact and are in thermodynamic equilibrium. Specifically, it is the potential difference between a point close to the surface of the first metal, and a point close to the surface of the second metal (or electrolyte). The Volta potential is named after Alessandro Volta. When two metals are electrically isolated from each other, an arbitrary potential difference may exist between them.
