Description: Presents batteries; electron flow; chemical action; current measured; transfer of electrons from copper to zinc; and more basic concepts of basic electricity., Explains that electricity is produced in three ways - by friction, by chemical action, and by magnetic action. Depicts Faraday discovering the principle of an induced current, and demonstrates with a small magneto generator the principle of current electricity.

Complete Record: Presents batteries; electron flow; chemical action; current measured; transfer of electrons from copper to zinc; and more basic concepts of basic electricity., Uses graphic illustrations and live-action sequences to identify and explain the following: batteries, current measurement, cell and chemical action, copper as positive terminal and zinc as negative, external circuit, and construction and uses of primary and secondary cells., , Explains that electricity is produced in three ways - by friction, by chemical action, and by magnetic action. Depicts Faraday discovering the principle of an induced current, and demonstrates with a small magneto generator the principle of current electricity.NOTE: Two (or more) records have been merged together to create this data.
