AC Motor Theory

Written for a college physics course, this midterm examination deals with electric and magnetic fields. When taking this test, learners answer multiple choice questions, solve problems, and analyze a variety of attractive diagrams....

The physics department at The University of Hawaii has designed midterm exams for their college physics courses. This version deals with electricity concepts. It requires learners to calculate conversions, capacitance, and potential...

My friend told me how electricity is measured and I was like Watt! In the hands-on activity, learners explore electricity by building circuits, both parallel and series. They also determine how increasing the number of light bulbs and...

The standard basics of electricity are detailed in this clear-cut collection of slides. Straightforward explanations are offered for static electricity, series and parallel circuits, conductors, insulators, and resistance. Some animation...

Wow! Here is a coherent and cleverly designed tool for teaching physical scientists about electric circuits. Animations help learners to visualize what is happening within the parts of a circuit. Components are displayed to teach them...

Electrical engineers entertain and explain how to construct an electromagnet-driven motor. Kellie and Mike, the hosts of the show, are enthusiastic teachers that will help introduce a project that you likely include in your middle school...

How does a direct current run a motor? Pupils control five variables in an electric motor and observe how the force diagram changes. The force, magnetic field, and current vary based on the changes in the design of the magnet and...

Students act as engineers to apply what they know about how circuits work in electrical/motorized devices to design their own battery-operated model motor vehicles with specific paramaters. They calculate the work done by the vehicles...

This wave and electromagnetism assignment is so thorough, it could be used as a unit exam. The first section of it covers wave concepts. The next section addresses static electricity. There is a section that deals with electric circuits....

I think I lost an electron. Are you sure? Yes, I'm positive! Starting with a hands-on demonstration and problem solving activity, young scientists define vocabulary related to circuitry and currents. Then they build their own circuits...
