Overview

Overview


Chapter 1 circuit terminology

Chapter 1: Circuit Terminology

  • Electronics

    • Devices – active vs. passive

    • Circuits

    • Systems


Cell phone architecture

Cell-Phone Architecture

Tech Brief 1: Micro- and Nanotechnology


Charge current

Charge & Current

  • Unit of charge = coulomb


Electron drift

Electron Drift

Response time = 0.2 microsecond

Actual travel time = 10 days!!


Current

Current


Example 1 1 charge transfer

Example 1-1: Charge Transfer

  • Given:

Solution:

Determine: (a) q(t)

(b)


Example 1 1 charge transfer cont

Voltage power

Voltage & Power


Reference ground

Reference/Ground

  • Choose reference point for potential

  • Assign potential at reference = 0, called ground

  • Now all potentials are relative to ground terminal


Measuring voltage current

Measuring Voltage & Current

  • Voltmeter: measures voltage without drawing current

  • Ammeter: measures current without dropping voltage


Open circuit short circuit

Open Circuit & Short Circuit

  • Open circuit: no path for current flow (R = )

  • Short circuit: no voltage drop (R = 0)


Power

Power

Rate of expending or absorbing energy

Energy conservation

Units: watts

One watt = power rate of one joule of work per second. 1 W = 1 A x 1 V


Passive sign convention

Passive Sign Convention


Example 1 4 energy consumption

Example 1-4: Energy Consumption

  • Given:Resistor consuming 20 W before switch turned off at t = 0.

    Also

  • Determine: Total energy consumed by resistor after t = 0.

  • Solution:

(before t = 0)


Circuit elements independent sources

Circuit Elements: Independent Sources


Circuit elements dependent sources

Circuit Elements: Dependent Sources


I v for sources

I-V for Sources

  • Current/voltage fixed for independent sources

    • What does a non-ideal source look like?

  • Dependent sources vary with reference voltage/current

    • What are units for slope?


Equivalent circuit using dependent source

Equivalent Circuit Using Dependent Source


Example 1 5 dependent source

Example 1-5: Dependent Source

  • Given:

Source is CCVS

Determine:

Solution:
