ENR 201 - Introduction to Electrical Circuits and Networks


Credits: 4
Lecture Hours: 3
Lab Hours: 2
This course provides the student with the basic tools needed to analyze the circuits and systems he/she will encounter in electrical engineering. Topics include basic circuit concepts, Kirchhoff’s Laws, basic network topology, mesh analysis, nodal analysis, superposition, Thevenin’s Theorem, Norton’s Theorem, maximum power transfer, initial conditions, the classical solutions of first and second order differential equations, sinusoidal steady state analysis, Phasor concepts, impedance and admittance, effective values, phasor diagrams, AC power relationships, power factor, apparent and complex power, pf correction, and 3-phase circuits. Laboratory assignments will require students to analyze data using computer programming skills, use of the software package Multisim for circuit analysis, and practice writing both formal and informal reports.
Prerequisite(s): Proficiency with computer software including word processing and spreadsheets
Corequisite(s): MAT 223  and PHY 152
