# AST 1065 - Electrical Principles

Credits: 3
Hours/Week: Lecture 2Lab 2
Course Description: This course covers electrical terms, what electricity is, what it does as it flows through a circuit, series and parallel circuits, Ohms Law, how to connect and use a DVOM, battery theory, and how to test batteries using a VAT-40. Students must be able to perform physical tasks to complete course requirements.
MnTC Goals
