EGR 285 - Electrical Circuits
Comprehensive overview of electrical circuits. Course covers units and definitions of charge, current, voltage, power, and energy. Other topics covered within the course include: Ohm's Law, active and passive elements, independent and dependent sources, resistance, Kirchhoff's Laws, network reduction, nodal and mesh analysis techniques, source transformation, superposition, Thevenin's and Norton's theorems, maximum power transfer and capacitance and inductance. Students will solve the natural, forced, and complete response of switched first order (RL, RC) and second order (RLC) circuits using differential equations. The course also covers the analysis of AC sinusoidal steady state, including AC sinusoidal steady state power, computer aided circuit analysis and ideal and practical operational amplifier circuits.
Prerequisite: MAT 182 Calculus II and EGR 289 Microprocessors
3 Class Hours
Learning Outcomes of the Course:
Upon successful completion of this course the student will be able to:
1. Define basic circuit elements (resistors, inductors, capacitors, independent sources, dependent sources), units, and quantities such as current, voltage, and charge.
2. Demonstrate a knowledge of circuit theorems (Ohm's law, KVL, KCL, current divider, voltage divider, superposition, source transformation, Thevenin equivalent, Norton equivalent and network reduction) by solving circuits that contain resistors, independent sources and dependent sources.
3. Analyze and solve resistive circuits using nodal and loop analysis which will also require solving simultaneous equations.
4. Design and analyze basic op amp circuits that add, subtract, multiply, integrate and differentiate. Students will be able to differentiate between the linear and saturation mode of the op amp. Students will be able to analyze op amps using the ideal or finite gain model.
5. State the physical characteristics and defining equations for the capacitor and inductor. Students will be able to integrate and differentiate lines, exponentials, and sinusoids.
6. State the definitions of forced response, natural response, steady state response, transient response, initial conditions.
7. Solve for the complete response of first and second order circuits where the sources are constants, exponentials or sinusoids using differential equations.
8. Solve for the sinusoidal steady state solution of circuits with sinusoidal sources. In addition, determine the average power for each device and power factor. Students will be able to correct the power factor of a circuit.
