Electric currentAn electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. In electric circuits the charge carriers are often electrons moving through a wire. In semiconductors they can be electrons or holes.
VoltageVoltage, also known as electric pressure, electric tension, or (electric) potential difference, is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a test charge between the two points. In the International System of Units (SI), the derived unit for voltage is named volt. The voltage between points can be caused by the build-up of electric charge (e.g., a capacitor), and from an electromotive force (e.g.
Francisco FrancoFrancisco Franco Bahamonde (fɾanˈθisko ˈfɾaŋko βa.aˈmonde; 4 December 1892 – 20 November 1975) was a Spanish military general who led the Nationalist forces in overthrowing the Second Spanish Republic during the Spanish Civil War and thereafter ruled over Spain from 1939 to 1975 as a dictator, assuming the title Caudillo. This period in Spanish history, from the Nationalist victory to Franco's death, is commonly known as Francoist Spain or as the Francoist dictatorship.
SpainSpain (España, esˈpaɲa), or the Kingdom of Spain (Reino de España), is a country located in Southwestern Europe, with parts of its territory in the Atlantic Ocean and across the Mediterranean Sea. The largest part of Spain is situated on the Iberian Peninsula; its territory also includes the Canary Islands in the Atlantic Ocean, the Balearic Islands in the Mediterranean Sea, and the autonomous cities of Ceuta and Melilla in Africa.
