Introduction

Chapter 1

Circuit Variables


1

Overview of Electrical Engineering

Power Systems (Classical ECE) Generators: nuclear,

hydro (water), thermal (coal,gas)

Power Lines: transmission lines, distribution

Grid System and Managment: efficient distribution of

electric power, redundancy to avoid black outs

ECE 4900 (Power Systems (?)) by Dr. Larry Zeng

ECE 1270: Introduction to Electric Circuits


2


Control Systems

Regulate and control processes

Control what? temperature (thermostat), pressure, flow

rate (oil refinery), fuel-air mixture in cars, motors, doors,

switches (everywhere), autopilot, sprinkler system and

irrigation system

ECE 4100 (Control Systems) by Dr. Larry Zeng



3


Computer Systems

Computing: Pocket calculators, computers,

supercomputers, embedded processors

Processors: Central Processing Unit (CPU),

Microcontroller unit (MCU), Digital Signal Processor

(DSP)

ECE 3610 (Digital Systems), ECE 3710 (Embedded Systems),

ECE 4710 (Real-Time Systems) by Dr. Fon Brown



4


Signal Processing

Transform electric signals into information: process

data from satellites, CT scanners, MRI, smart phones

ECE 3210 (Signals and Systems), ECE 4210 (Digital Signal

Processing) by Dr. Larry Zeng



5


Communication Systems

Generate, transmit and distribute information: radio,

cell phones/smart phones, satellite communication systems,

radio telescopes, wireless communication

ECE 3110 (Microelectronics I), ECE 3120 (Microelectronics

II) by Dr. Justin Jackson, ECE 4410 (Communication Circuits

and Systems) by Dr. Chris Trampel



6


Sensors and Sensor electronics: gather data to be

processed later

Electromagnetics: classical study of electrostatics

(capacitors), magnetostatics (inductors) and Maxwell’s

equations

Power of Ten


13Electric Effects: Voltage and Current

Positive Charge

Negative Charge

Voltage is due to separation of Charge=Electric Force

Current is due to motion of Charge=Electric Flow

15Passive Sign Convention

i

+

- Current flows from positive terminal to negative

terminal (positive charge moves from positive to negative)

It can be a Resistor, Capacitor, Inductor or in general any

circuit element
