Question 1: What is a rheostat?

a specialized mobile phone for construction workers an ammeter with additional capabilities a device to measure hertz a device used to vary the resistance in an electrical circuit

Answer:

a device used to vary the resistance in an electrical circuit Question 2: Which tool can measure electrical potential between two points in a circuit?ohmmeter ammeter voltmeter There are no tools for this purpose.

Answer:

voltmeter Question 3: A real-world usage of multiplexing could be: a telecommunications company using several different laser light colors in the same fiber line to increase overall throughput.all of these are examples of multiplexing.a mobile phone service provider setting up a tower to "listen" to multiple cell phone calls at one time.a media company using two microphones to provide the same audio signal to seventeen independent audio recorders during a press conference.

Answer:

all of these are examples of multiplexing.

4,500 350 500 5,000

Answer:

5,000

Question 5: What is the resistor code color for a resistance of 6?

jade green pink blue red

Answer:

blue

Question 6: What position is a push-to-break switch usually in?

half power emergency mode only off on

Answer:

on Question 7: When using a digital multi-meter to measure the voltage in a circuit, the leads should be connected...in series between the power source and load.in-line with a fuse.in parallel to the power source.only after shutting the circuit power off.

Answer:

in parallel to the power source.Question 8: Some of the advantages of optical data transfer (via optical cable) versus wireline

data transfer are: (choose all correct answers)

a higher theta value resulting in multiplexed transmissions.the potential for louder volumes when the cable is used for digital audio.increased resistance to tampering / unauthorized signal interception.

reduced possibility of unwanted interference from electromagnetic sources.

Answer:

increased resistance to tampering / unauthorized signal interception.reduced possibility of unwanted interference from electromagnetic sources.Question 9: When wiring 110V / 120V AC power (in the United States of America), what is the standard accepted color of the neutral wire?black red white green

Answer:

white
