Part of the "A 3-D Demonstration" series. Presents both the theory of electric circuits and basic practical methods of managing circuits safely. Investigates the benefits and dangers of ground circuits together with safety devices, such as fuses and ground fault interrupters. Introduces the concept of electric resistance. Specific modules include Completing a Circuit, Fuses, Circuit Breakers, Ground Circuits, Ground Faults, Ground Fault Interrupters, Resistance, and Electrical Resistance. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).

Part of the animated "Johan, the Young Scientist" series. While waiting for his rechargeable batteries to charge up, Johan discovers in ScienScape that electricity is generated by cranking up a dynamo. Professor Hoo then sends him, Ani, and Moki to find how different power stations use different methods of generating electricity.
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.
Can people in remote rural areas who are far from electric generating plants get power for their lights and appliances? Solar cells make it possible. Mechanical and electrical engineers at the US Department of Energy's Sandia National Laboratories take viewers through the process of designing and installing solar cell panels in remote locations.
The Three Gorges Dam is the largest hydro-electric dam in the world. Yet questions abound over environmental and social issues, not to mention the logistic problems of moving ships up and down the river. An ingenious system of ship locks has gone towards solving that problem, echoing the techniques of Banaue farmers in the Philippines who mastered the art of managing water over two thousand years ago.
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.
Students explore the various properties of magnets and the characteristics of magnetic force. Graphics and real-life footage explain how magnets are used in generating electricity. Electromagnets and their many uses are demonstrated as well. Other terminology includes: magnetic poles, magnetic field, electric motor, generator, solenoid, and electromagnetism.
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.
Graphene could make it possible for electricity to move effortlessly through computer chips, thereby allowing computer systems to run faster than ever before. Savings in both heat and energy costs could have graphene replacing silicon as the basis of computer chip construction. Part of the Fast Draw Series.
Adabot learns about electricity after tripping a circuit breaker. Ladayada explains that electricity is measured in amperes. They also use a multimeter to measure the number of electrons in a circuit. Part of the "Circuit Playground" series.
Part of the "A 3-D Demonstration" series. Defines electric power and explores in general terms a variety of means by which it is produced, transmitted, and consumed. Discusses energy conservation in relation to power production, transmission, and consumption with a particular focus on the efficiencies and inefficiencies associated with the conversion of electricity to light. Specific modules include Efficiency I: Power Production, Power, Efficiency II: Power Transport, Power Transmission, Power Consumption, Inefficiency I: The Light Bulb, and Inefficiency II: The Fluorescent Bulb. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Part of the "A 3-D Demonstration" series. Explores basic electricity as it was perceived by Benjamin Franklin and other early theorists as well as the principles of positive and negative charge, conduction and induction, atoms and electrons, and elementary charge. Relates Coulomb's Law in detail, including the torsion balance experiment, that led to a breakthrough in scientific theory related to electricity.
In Bruce Logan's lab at Penn State University, researchers are working on developing microbial fuel cells (MFC) that can generate electricity while accomplishing wastewater treatment. In a project supported by NSF, they are researching methods to increase power generation from MFCs while at the same time recovering more of the energy as electricity. Through their research projects, Logan’s team has already proven that they can produce electricity from ordinary domestic wastewater.
Join Dr. Knowledge as he takes young viewers on a fast-paced adventure to learn about energy and electricity. Shows what tools, appliances, factories, and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. K and the Inquisitive Minds team trace the electricity from the wall through the power grid to its source.
Learn the story behind the steam engine, electricity, and other important inventions. From the Kool Books series narrated by Hector Bonilla.
Using only gasoline to power cars back in 1905 was cheaper and easier, so the hybrid car was forgotten-until recently. The modern hybrid car has two distinct power sources working together to make it run: gas and electric power. Since the fuel widely used now is a non-renewable resource and becoming increasingly less affordable, the hybrid car is making a comeback. The benefit of the hybrid is that instead of running on gas, it uses non-polluting electric power when possible. Also, it helps cut pollution and saves drivers money at the gas pump.
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.
Follow the history of hydroelectric energy and explore the process of turning the down flow of water into usable energy. Shows the function of the turbine and water level at the hydroelectric dam, as well as the scale of a dam construction.
Hans, the integrated circiuit (IC), stops by the lab and explains the role of ICs in an electrical circuit. Part of the "Circuit Playground" series.
