PLTW ENGINEERING ESSENTIALS UNIT 3 EXAM 2024-2025
QUESTIONS WITH 100% CORRECT ANSWERS.
Algorithm - Answer: - An ordered set of instructions that are used to carry out a task.
Analog - Answer: - A way of representing some physical quantity, such as temperature or
velocity, by a proportional continuous voltage or current. An analog voltage or current can have
any value within a defined range.
Boolean Expression - Answer: - A processing decision branch using comparison operators
(i.e., = ≠ > <) that is defined to return a Boolean value ("true" or "false"). By using a Boolean
expression to ask questions, the program can determine what to do next.
Circuit Schematic - Answer: - A graphical model of an electrical circuit.
Conditional - Answer: - A command that performs different actions depending on whether a
condition is true or false.
Current - Answer: - The flow of electrical charge through a circuit measured as an ampere.
Digital - Answer: - A way of representing a physical quantity by a series of binary numbers. A
digital representation can have only specific discrete values.
Electrical circuit - Answer: - A system that converts electrical energy into another form of energy.
Event handlers - Answer: - In the MakeCode editor, a control block that looks for inputs or
events to know when to perform a specific action.
Executable Code - Answer: - An algorithm that is expressed in a programming language that
can be understood and followed by a computer.
Flow Chart - Answer: - A diagram that represents an algorithm, work flow, or process and uses
geometric symbols connected by arrows to show the direction of the flow of action.
Multimeter - Answer: - An electrical device that typically measures voltage, current, and
resistance.
Pseudocode - Answer: - An executable code development technique that allows you to work
out the logic without the full precision of the programming language specifics.
Resistance - Answer: - The opposition to current measured as an ohm.
Truth Table - Answer: - A list of all possible input values to a digital circuit, listed in ascending
binary order, and the output response for each input combination.
Voltage - Answer: - The amount of work to be done to move a charge from one point to
