## Description

An electric system consists of all of the elements needed to distribute electrical power. This course will first introduce you to current, charge, and voltage. You will study how electrons from a voltage or current flow on circuits and how capacitors store an electrical charge. You will also study the three types of transducers and how they convert energy from one form to another. The course will then discuss the two types of current, the properties of magnets, and Faraday's law of magnetic induction.

You will then explore sound and study electromagnetic waves and mechanical waves. You will study the wave equation which is the mathematical relationship between the speed of a wave, its wavelength, and frequency. Next, you will learn about sound diffraction, which is the bending of sound as it travels through an aperture or past an obstacle. Finally, you will study the intensity of sound and speed of sound and learn that sound waves travel fastest through solids.

Physics can be a difficult subject to study, and it's quite likely that there have been days when you weren't really listening to your professor teach in class. This course will stitch together the missing pieces and help you understand the main concepts of physics at your own pace and time. And with so much to learn, from the nature of sound, magnetic and standing waves, to the speed of sound and its importance, why not check out the course today and start getting ahead, for free.
