 Electric circuit A closed path along which electrons that are powered by an energy source can flow Voltic cell A source of energy that generates an electric current by chemical reactions involving two different metals or metal compounds seperated by a conducting solution Battery A connection of two or more cells Electrode One or two metal terminals in a cell or battery Electolyte A solution or paste that conducts charge  Dry cell A cell that contains an electrolyte made of paste Wet cell A cell that contains a liquid electrolyte Priamary cell A cell that can be used only once Secondary cell A cell that can be used more than once or recharged Fuel cell A cell that generates electricity through cemical reactions of fuel that is stored outside Solar cell A cell that converts sunlight into electrical energy Terminal A position on a cell that must be connected to other components to form a circuit Switch A control device that can complete or break the circuit to which it is connected to Open circuit A cicuit that contains a gap or break Electric current A mesure of the number of charged particles that pass by a point in an electric circuit each second Coulumb(C)  The quantity of charge that is equal to  the charge of 6.25x1018 Ampere(A) The unit of electric current, equivelent to one coloumb per second Electric resistance The property of a substance that hinders elecric current and converts electrical energy into other forms of energy Resistor A device used in an electrical circuit to decrease the current throught a component by a specific amount Load A resistor or any other device that transforms electrical energy into heat,motion,sound,or light. EX: light,buzzer Potential difference(Voltage) The difference between the electric potential energy per unit of charge at two points in a circuit Volt The unit for potential difference;equivelent to one joule(J) Per coloumb(C) Cicuit diagram A diagram that uses standard symbols to represent the compounds in an electric circuit Series circuit A circuit in which there is only one path along the electrons can move Parellel circuit A cicuit in which there is more than one path for the electrons can flow Ohms law The ratio of potential difference to current in a constant called resistance Ohm(symbol not found on keyboard) The unit of resistance equivelent to one volt per ampere(V/A) Superconductor A material through which electrons can flow with no resistance Non-ohmic Not following ohms law Loads in series As more loads are added to the series more resistance is added and is simmilar to increasing the lenghth of the wire Loads in parallel The current entering a parellel connection divides thus, the  sum of current entering equals the current entering the connection AuthorAamir101 ID180858 Card SetChapter 11 glosary terms DescriptionChapter 11 glossary terms Mrs.DAY Updated2012-10-31T00:15:27Z Show Answers
