Students explore electric current and the role it plays in electrical circuits. They also compare parallel and series circuits. The video concludes by demonstrating some fundamental concepts of electrical safety. Other important terminology includes resistance, switch, fuse, circuit breaker, short circuit, ground prong, and electric potential difference.

Explore the dynamic work environment of an electrical engineer who oversees large industrial projects. Watch as engineers interact with one another and use cutting-edge 3-D modeling. Learn how to become a licensed professional engineer. Part of the "Career Connections" series.
Functional electrical stimulation technology (FES) is designed to interface technology with muscles and nerves in an attempt to restore some level of function for people with central nervous system disabilities. Visits several experimental programs that are using implanted electrodes, controlled by external computer devices, to enable people with spinal cord injuries to stand, transfer, and, under controlled conditions, even walk.
Revolutionary technologies now make it possible to harness a completely renewable energy resource-the natural power of the sea. Explores ways that electric power can be drawn from tidal forces or from fluctuations in ocean currents. Highlights several innovations, including a tide-driven rotor off the coast of Cornwall in the United Kingdom, a multi-rotor locks system in the English Channel, an OTEC (i.e., ocean-thermal energy conversion plant) in southern Japan, and another OTEC facility in Hawaii. Commentary from the inventors, designers, and managers of these systems is included along with animation that illustrates how each mechanism works.
Adabot and Minerva are having difficulty talking with one another over the walkie-talkies. There is too much "noise." Minerva helps Adabot understand the phenomena of electrical noise. Part of the "Circuit Playground" series.
Adabot learns all about diodes and their role in an electrical circuit. Diodes act as a safety feature and ensure the electrical current flows in the correct direction. Part of the "Circuit Playground" series.
In this episode, the researchers in the A to Z Career Lab investigate the roles and responsibilities of electricians. Individuals in this profession specialize in electrical wiring of buildings. Part of the "I Can Be Anything I Want to Be A to Z" series.
Capacitors and batteries store electrical energy, but they also have different functions in a circuit. Adabot and Ladyada discuss those differences, and Cappy, the capacitor, explains how capacitors work in an electrical circuit. Part of the "Circuit Playground" series.
Students learn the fundamental concepts of electrical energy. Easy-to-understand animations illustrate the concepts of electric charge and electric current. Static electricity and the role it plays in creating lightning is also described. Important terminology includes protons, electrons, repel, attract, charges, charged objects, electrical discharge, electric field, and electric force.
Energy is all around and in many forms. Real-life examples of energy provide relevance and meaning to students. Special emphasis is paid to heat energy and how it can be measured. Concepts and terminology explored include energy of motion, light, sound, electrical energy, heat, and thermometer.
Harnessing energy from the waves of the world’s oceans seems like the ultimate in renewable fuel. With funding from the National Science Foundation, Electrical engineer Annette von Jouanne is leading efforts to capture wave energy, by creating simple, powerful devices that can withstand heavy winds, monster waves, and corrosive salt water. Oregon State University research now underway is based on ocean buoy generators. As ocean swells hit the buoy, electrical coils inside move through a magnetic field, inducing a voltage, and creating electricity.
Observe changes to electrostatic force as you play with the distance between charges and charge amounts at both macro and atomic scales.

Join Adabot and friends for a campfire musical. They will learn all about Ohm's Law: the foundation of electrical engineering. Part of the "Circuit Playground" series.
Silver is a chemical element with the symbol Ag and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
Semiconductors are in everything from cell phones to rockets. But what exactly are they, and what makes them so special? Find out from an electrical engineer. Part of the "Science Out Loud" series.
Uses microphotography and graphics to examine different kinds of plant and animal cells, discussing their structures and tissues. Defines mitosis and meiosis as forms of cell division and illustrates each. Video has three 5-minute segments for convenience.
Not only can lightning strike twice, but it can also strike the ocean. Individuals must take certain safety measures when surrounded by water during a storm. Part of the "NOAA Ocean Today" series.
