## Theory, Measurement, Control, and Applications of Electrical Energy

### Unit Overview / Details

In this unit the student will learn about the types of energy, the measurement of work and power, sources forms of energy, controls, and be able to apply electrical power to devices.

Classroom
7 Hours

### Concepts/Contents

• List types of current and explain how electricity is produced
• state how electricity is measured
• Name different types of electrical circuits and give examples of their uses
• Identify electricity and magnetism
• Select wire sizes and other electrical components for specific applications
• Design simple electrical circuits to meet specific criteria.

### Lessons in this Unit

• Required time
55 Minutes
Set up: Students should have already un-packed FRC kit of parts and inventoried power system components
0 Minutes
• Students will demonstrate an understanding of both cathode and anode 7-segment displays as they are able to wire them and set up simulations of how they would function to display their desired message. The lesson will build upon students prior knowledge with these displays as it uses calculators familiar to the students.

• Students will gain familiarity and experience with And, Or, Inverter gates and see examples of practical uses of these different logic gates. The lesson will be made real to them as they create a game that mimics the popular TV show  "Are You Smarter than a 5th Grader?". Students will follow the design process in creating their solution to the game design parameters found in the accompanying design brief.

• Students will take the "guts" of their solution to part 1 of this lesson and implement it into an efficiently designed housing that will demonstrate an ability to conserve materials, keep down costs, and creatively design a product that can be taken to market.

• Students will be introduced to the theory behind the two sources of electrical power. They will be given a chance to build on prior knowledge of direct current circuits and then expand that knowledge to include the workings of alternating current circuits. This lesson will provide a base for understanding direct current circuits the remainder of the year.
