Technology Notes Flashcards
What are the three categories of matter?
Conductors, Semiconductor and Insulators
What is conductor?
Substances that permit the flow of electrical charges
What is Semiconductor?
Substances of variable conductivity depending on several factors
What is Insulator?
Substances that delay the flow of electric current.
What is Conductance?
The capacity of material allowing electricity to flow through them
As the length increases, conductance_____
Decreases
As the diameter increases, conductance_____
Increases
As the temperature of the wire increases conductance____
Decreases
What is Power Supply?
The ability to provide energy to electrical current in a circuit
What is “protection”?
Allows the safe use of electrical circuits and appliances when they are under a power surge
What is “Transformation”?
The ability of circuit elements to transform electrical energy into other useful forms of energy.
What is “Control?”
Allows the circuits to be easily turned on and off
What is “Constraint”?
Constraint are external forces that are exerted on materials and that have a tendency to deform them.
What is Motion transmission?
Relaying a motion from one part to another without altering the nature of the motion.
What does a motion transmission system contain?
- a driver component
- a driven component
- Intermediate component
