# ENG 260 - Electrical Engineering

3 Credits, 3 Contact Hours
3 lecture periods 0 lab periods

Introductory survey of the electrical engineering discipline with emphasis on electrical power applications. Includes resistive circuits, inductance and capacitance, transients, steady-state sinusoidal analysis, and logic circuits. Also includes operational amplifiers, microcomputers, and diode electronics.

Prerequisite(s): MAT 231  and PHY 216IN .

Course Learning Outcomes
1. Demonstrate the ability to apply Node Voltage Analysis and Mesh Current Analysis equations for circuits containing dependent and independent sources and resistors.
2. Demonstrate the ability to reduce complex circuits to Thevenin (or Norton) equivalent circuits.
3. Demonstrate the ability to use transient analysis to find the value of any current or voltage in resistor-inductor (RL), resistor-capacitor (RC), and resistor-inductor-capacitor (RCL) circuits.
4. Demonstrate the ability to apply phasors to solve mesh and node problems in alternating current (AC) circuits.
5. For a given combination of load impedance, applied voltage and through-current, demonstrate the ability to determine any of the following quantities: average and reactive power, power factor, complex power, and rms voltage and current values.
