Basic AC Circuits
WVEIS 1783
This course introduces the student to the knowledge base and technical skills for Basic AC Circuits. Areas of study
include alternating current, circuit evaluation, magnetic, and electromagnetic devices. Emphasis will be placed on career
exploration, job seeking skills, and personal and professional ethics. Safety instruction is integrated into all activities.
Students will utilize problem-solving techniques and participate in laboratory activities to develop an understanding of
course concepts, and teachers should provide each student with real world learning opportunities and instruction related
to Electronic Technology occupations. Students are encouraged to become active members of SkillsUSA for additional
co-curricular opportunities that enhance student achievement, develop student leadership, and support experiential
learning. The West Virginia Standards for 21st Century Learning include the following components: 21st Century Content
Standards and 21st Century Learning Skills and Technology Tools. All West Virginia teachers are responsible for
classroom instruction that integrates learning skills, technology tools, and content standards and objectives.
