In this course you will learn about:
This podcast (audio) file explains how electric current can be obtained from the sun through the solar panel using direct illumination of the sun rays
To lay the foundation for understanding what trigonometry is and how it works, do this next activity.
Introduction to magnetism: Wikipedia article that provides an overview of the concept.
The force that acts across the air gaps between magnets is the same force that creates wonders such as the Aurora Borealis. In fact, magnetic effects pervade our lives in myriad ways, from electric motors to medical imaging and computer memory. In this chapter, we introduce magnets and learn how they work and how magnetic fields and electric currents interact.
Electrical devices convert the electrical energy carried by the charges into other types of energy such as heat, sound, and motion. Components in the appliance resist the flow of charge and are referred to as resistors. In this unit1 you will understand what resistance is, the factors that affect the resistance and the relationship between resistance and current.
