Chapter 1: Statics and Forces

What is a feature of through-hole assembly?

Short answer: Leads go through holes and are soldered

Through-hole technology inserts component leads through board holes and solders them on the opposite side.

Groan of the day: Through-hole goes right through it.

Sources: Electronics

What does electronics study and apply?

Short answer: Principles of physics to control charged particles

Electronics applies physics principles to design and operate devices that manipulate electrons and charged particles.

Groan of the day: Electronics is charged with ideas.

Sources: Electronics

What does the semiconductor industry drive?

Short answer: Advancement of electronics

The semiconductor industry continually produces more sophisticated devices and circuits, driving electronics forward.

Groan of the day: Semiconductors are the real MVPs.

Sources: Electronics

What advantage did the MOSFET bring?

Short answer: It could be miniaturized and mass-produced

The MOSFET was compact, scalable, affordable, low power, and high density, revolutionizing electronics.

Groan of the day: MOSFETs make small big.

Sources: Electronics

What is digital logic the basis of?

Short answer: Digital computers and microprocessors

Digital circuits use Boolean algebra and are the basis of digital computers and microprocessor devices.

Groan of the day: Logic is the computer's backbone.

Sources: Electronics

What is electronic noise?

Short answer: Unwanted disturbances on a useful signal

Noise is unwanted disturbance that obscures signal information and is not the same as distortion.

Groan of the day: Noise is not music to circuits.

Sources: Electronics

What does a resistor do in a circuit?

Short answer: It opposes the flow of current

Resistors are passive components that limit or oppose current flow, helping control voltages and currents in a circuit.

Groan of the day: Resistors have great resistance to drama.

Sources: Electronics

What does a capacitor do?

Short answer: It stores electrical energy

Capacitors are passive components that store electrical energy, useful for filtering and timing in circuits.

Groan of the day: This capacitor has a lot of potential stored up.

Sources: Electronics

What is an integrated circuit?

Short answer: A group of components on one chip

Integrated circuits package many components together on a single semiconductor block to form complex circuits.

Groan of the day: This chip has integrated into the group.

Sources: Electronics

What do logic gates range from?

Short answer: Simple gates to large integrated circuits

Digital circuits range from simple logic gates to large integrated circuits with millions of gates.

Groan of the day: Logic gates open the door to computing.

Sources: Electronics

What does a voltage comparator output?

Short answer: One of two levels

A voltage comparator receives a continuous voltage range but outputs only one of two levels, like a digital circuit.

Groan of the day: Comparators compare and decide.

The cheat sheet

The whole guide on one screen. Screenshot it, print it, stick it on the fridge.

  • Safety precautions protect you from burns, shocks, and damage. Learn and follow them before using, building, altering, or repairing electronics.
  • Schematics use standard symbols for parts like resistors, capacitors, and transistors so others can read and build the circuit.
  • Labels tell readers which part is which, making the diagram clear and usable for building or troubleshooting.
  • Active components like transistors and thyristors control current flow at the electron level, enabling switching and amplification.
  • A PCB holds and connects electronic components to form a working circuit.
  • Digital logic uses gates and binary states to process information in circuits and computers.
  • Analog circuits handle continuous voltage or current, such as signal amplification.
  • Analog circuits condition signals from sensors, useful in measurement and control.
  • Digital circuits use binary with two voltage levels, often low for 0 and high for 1.
  • Binary 101 equals 4 plus 0 plus 1, which is 5 in decimal.
  • Binary 110 equals 4 plus 2 plus 0, which is 6.
  • One project option is a control device, built from a schematic and explained to your counselor.

Pop quiz

Think of your answer first, then peek.

  1. What should you do before soldering or repairing an electronic device?
    • Describe and follow safety precautions
    • Skip safety steps to save time
    • Only wear gloves
    Show the answer

    Describe and follow safety precautions. Safety precautions protect you from burns, shocks, and damage. Learn and follow them before using, building, altering, or repairing electronics.

  2. What is binary 110 in decimal?
    • 8
    • 6
    • 4
    Show the answer

    6. Binary 110 equals 4 plus 2 plus 0, which is 6.

  3. What else should you research about a career besides training?
    • Only the parking lot
    • Only the logo
    • Employment prospects and salary
    Show the answer

    Employment prospects and salary. Research employment prospects, starting salary, advancement, and career goals.

  4. Why must heat be removed from electronic circuitry?
    • To prevent failure and improve reliability
    • To make it louder
    • To change its color
    Show the answer

    To prevent failure and improve reliability. Heat must be dissipated to prevent immediate failure and improve long-term reliability.

  5. How can electronics be used for a control purpose?
    • By making light
    • By using inputs, outputs, and controllers
    • By only storing data
    Show the answer

    By using inputs, outputs, and controllers. Electronics can control things using inputs, outputs, and controllers working together.
