# ATMN 110 - Electrical Circuit Analysis

3 Credit: (1 lecture, 2 open-lab, 0 clinical) 3 Contact Hours:  [Math Level 3  or INDS 122 ]

This course teaches fundamentals of AC/DC electrical systems used for power and control in industrial, commercial, agricultural, and residential applications using the Amatrol training system. Students learn industry-relevant skills included in subject areas such as Basic Electrical Circuits, Electrical measurement, Circuit Analysis, Inductance and Capacitance, Combination Circuits, and Transformers.

Also introduced in this class is Electric Relay Control and relay logic control circuits used in industrial applications. Ladder Diagrams are explained and learners connect, operate, and design a ladder diagram using one or more logic elements. Additional concepts include sequencing control, including relay operation, relay application, limit switch operation and application; and timers and advanced systems including time-delay relays, multiple cylinder control, and machine modes of operation.
