### 1. Circuit Terminology

CIRCUITS by Ulaby & Maharbiz

Chapter 1: Circuit Terminology

- Electronics
- Devices – active vs. passive
- Circuits
- Systems

Tech Brief 1: Micro- and Nanotechnology

Charge & Current

- Unit of charge = coulomb

Example 1-1: Charge Transfer (cont.)

(b)

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

- Voltmeter: measures voltage without drawing current
- Ammeter: measures current without dropping voltage

Open Circuit & Short Circuit

- Open circuit: no path for current flow (R = )
- Short circuit: no voltage drop (R = 0)

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

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: Dependent 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?

Tech Brief 2: Moore’s Law

Tech Brief 2: Moore’s Law

- Challenges to Continuation of Moore’s Law
- Heat dissipation
- Size (approaching atomic dimensions)
