Still image from Current Electricity

Part of the "A 3-D Demonstration" series. Explores how electric energy became an essential tool with the advent of electricity storage, allowing the flow of current to do useful work. Defines and examines conductors, insulators, voltage, and current, using a water flow model to help ensure understanding. Explains the difference between electron flow and current flow models. Also develops the nature of direct and alternating current (both one- and two-phase). Specific modules include Tapping a Source, Conductors and Insulators, Direction of Flow, Potential Difference, Measuring Voltage, Measuring Current, Alternating Current, and AC Voltage. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act). Accessibility options on the DVD are: (1) expanded description, (2) English subtitles in a black box, (3) subtitled description.
