battery: A device that can convert chemical energy into electrical energy.
chemical: A substance formed from two or more atoms that unite (bond) in a fixed proportion and structure. For example, water is a chemical made when two hydrogen atoms bond to one oxygen atom. Its chemical formula is H2O. Chemical also can be an adjective to describe properties of materials that are the result of various reactions between different compounds.
chemical engineer: A researcher who uses chemistry to solve problems related to the production of food, fuel, medicines and many other products.
chemistry: The field of science that deals with the composition, structure and properties of substances and how they interact. Scientists use this knowledge to study unfamiliar substances, to reproduce large quantities of useful substances or to design and create new and useful substances. (about compounds) Chemistry also is used as a term to refer to the recipe of a compound, the way it’s produced or some of its properties. People who work in this field are known as chemists.
current: (in electricity) The flow of electricity or the amount of charge moving through some material over a particular period of time.
electric current: A flow of electric charge — electricity — usually from the movement of negatively charged particles, called electrons.
electricity: A flow of charge, usually from the movement of negatively charged particles, called electrons.
electrode: A device that conducts electricity and is used to make contact with the non-metal part of an electrical circuit, or that contacts something through which an electrical signal moves. (in electronics) Part of a semiconductor device (such as a transistor) that either releases or collects electrons (negative charges) or holes (positive charges) — or that can control their movement.
engineer: A person who uses science and math to solve problems. As a verb, to engineer means to design a device, material or process that will solve some…
