Announcement Next class: 10 min Quiz Material: Book Chapter 10 Circuits (covered in class examples)
Objectives • Discuss FE exam • Continue with Fundamentals of Electric Circuits
Fundamentals of Engineering (FE) Exam • The FE exam is the step in the process to becoming a professional licensed engineer (P.E.) • https://ncees.org/engineering/fe/ • General FE exam: Section 14. Electricity, Power, and Magnetism: • A. Electrical fundamentals (e.g., charge, current, voltage, resistance, power, energy) • B. Current and voltage laws (Kirchhoff, Ohm) • C. DC circuits • D. Equivalent circuits (series, parallel, Norton’s theorem, Thevenin’s theorem) • E. Capacitance and inductance • F. AC circuits (e.g., real and imaginary components, complex numbers, power factor, reactance and impedance) • G. Measuring devices (e.g., voltmeter, ammeter, wattmeter
FE Example: If R1 =R2=R3=R4 = 10Ω and R = 20Ω, what is the equivalent resistor of the circuit?
Example Solution • Req =(1/R2+ 1/R3)-1 + R4 + R • R eg =(1/10+1/10)-1 + 10 +20 = 35Ω
