1. Announcement Next class: 10 min Quiz Material: Book Chapter 10
Circuits (covered in class examples)

2. Objectives Discuss FE exam
Continue with Fundamentals of Electric Circuits

3. Fundamentals of Engineering (FE) Exam
The FE exam is the step in the process to becoming a professional licensed engineer (P.E.)
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

4. FE Example: If R1 =R2=R3=R4 = 10Ω and R = 20 Ω,
what is the equivalent resistor of the circuit?

7. Example Solution Req =(1/R2+ 1/R3)-1 + R4 + R
R eg =(1/10+1/10) = 35Ω

8. More Complex Problem Use Ohm’s Law for Ix …… Answer: 5V, 1A
