1966 Upper Voltan coup d'état 1966 Upper Voltan coup d'état The 1966 Upper Voltan coup d'état was an event which took place on 3 January 1966 in the Republic of Upper Volta (today Burkina Faso), when following large-scale popular unrest the military intervened against the government, forced President Maurice Yaméogo to resign, and replaced him with Lieutenant Colonel Sangoulé Lamizana. Lamizana would go on to rule until 1980, when yet another military "coup d'état" overthrew him. The 1966 coup would prove to be the first in a long line of Upper Voltan and later Burkinabé coups, both failed and successful such, and marked the beginning
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.
