Engineering Essentials Final Exam
Review Exam Questions With
100% Correct Answers.
What three features must every circuit contain? - Answer - 1. a power source
2.a load
3.a path
What is the difference between an analog circuit and a digital circuit? - Answer - An
analog circuit can respond to more broad values than just 0 and 1. However, a
digital circuit has only two discrete values or logic levels represented by 0 or 1.
What is a truth table? - Answer - a list of all the possible input values to a digital
circuit, listed in ascending binary order, and the output response for each
combination
What two values can be entered into a truth table? - Answer - 0 and 1
What are three aspects of laparoscopic surgery? - Answer - 1. small incisions
2.use of cameras
3.faster recovery
What are some products/projects that an electrical engineer would be involved in? -
Answer - smallscale electronics, computer hardware, power and energy, and
telecommunications
How does the North American Power System work? - Answer - The power system is
interconnected throughout North America. Each power plant contributes to the
entire system, and energy can be transferred from one region to the other based on
demand.
How is energy made available to you at your house? - Answer - 1. Electricity is
converted at the power plant.
2.Transported through conductors to my house.

, 3.AC power is in the outlets, but it needs to be converted to DC power to be used by
electronics.
What are five different types of energy? - Answer - 1. hydroelectric
2.coal
3.solar
4.Biofuel and biomass waste
5.Natural gas
What are the three properties of a circuit and what do we use to measure each? -
Answer - 1. The voltage of a power source determines its ability to move a charge
around a circuit. We use a voltmeter to measure the voltage with a unit of a volt.
2. Resistance is the opposition to current. We use an ohmmeter to measure
resistance with a unit of ohm, abbreviated as Ω.
3. Current is the measurement of the flow of the electric charge. We use an
ammeter to measure current with a unit of measurement of an ampere, abbreviated
as A.
According to Ohm's Law, what happens to the current in a circuit when resistance is
decreased? - Answer - If we decrease the resistance in a circuit, then the current
will increase.
What is the equation for Ohm's Law? - Answer - Current (I) = V/R
Voltage (V) = IR
Resistance (R) = V/I
What must be used with an LED in a circuit to avoid the LED being destroyed? -
Answer - a resistor
What is the color band sequence of a 440 ohm resistor? - Answer - yellow-yellow-
brown
What are the steps of the design process? - Answer - 1. Define Problem
2.Generate Concepts
3.Develop Solutions
4.Construct and Test
5.Evaluate Solution
