watt element would be rated at what amps when testing for excessive EMF emission near a conductor
or appliance the tool of choice is a what?
Answer:
15 amps
Question:
what is the symbol for a variable resistor the primary problem with using a series circuit to supply
loads is what? based on this section the most common electrical circuit problem in marine applications
is? the primary by-product of excessive electrical resistance is? one horse power equals 746 watts
excessive electrical resistance can be caused by? what can cause a intercircuit short
Answer:
gauss meter variable resistor voltage drop through the circuit will be excessive unwanted opens heat
undersized wire, loose connections, and corrosion wire chafe or a errant screw that finds its way into a
wire
Question:
what is a short circuit to ground what is a internal short
Answer:
when a hot wire makes contact with a ground before the current reaches the device. is normally a short
inside a load possibly caused by water getting
Question:
which one is a series circuit
Answer:
into a device or installing it in a area with out proper ventilation
Question:
which one is a parallel circuit
Answer:
, Question:
which one is ohms law
Answer:
Question:
which one is power formula
Answer:
Question:
when using ohms law if any two values are known the third can be found by using if resistance
decreases and the voltage remains constant in a circuit then the amperage will the unit of measure for
power is? a microwave with a wattage of
1.2KW and a 120 VAC draw how
many amps does it draw engine starter circuits are not required to have what? in a series circuit the
amperage is? in all circuits voltage is lost as it travels through the circuit which is commonly referred
to as? the most common type of circuit fault is a? what is the most common type of circuit fault is? the
most dangerous type of short circuit is? while there's some variation among countries in North
America the preferred colors for 120 VAC is what?
Answer:
multiplication or division increase watts 10 amps overcurrent protection the same every it is measured
voltage drop open circuit open circuit short circuit to ground black, white, green
Question:
if conductors color coding is not enough alternative labeling may be used for DC conductors as long
as a ________ is provided in the boats documentation when AC and DC conductors converge at the
black of panelboards the use of ________ insulation for DC negative conductors gives a quick and
distinctive differentiation between DC negative and AC hot conductors the insolation on grounding
conductors should be either? a time-domain reflectometer (TDR) can confirm continuity and? most
wiring-related problems occur where? for battery cable gauge sizes the tool of choice for terminations
is referred to as a _ ____ which leaves a square crimp on the terminal minimal support for wire
bundles should occur at least every ____ inches, according to standard E-11.14.4.1.9. voltage drop is
not considered with AC because __ _. conductors used for lighting other than navigation lights and
other circuits where voltage drop is not critical shall be sized for a voltage drop not to exceed ___ ?
when AC and DC conductors are run together AC conductors shall be ___ ? no more than _____
terminals shall be secured to any terminal stud? most technicians think of the ungrounded conductor as
_____ when working with AC or DC circuits a disadvantage of a time domain reflectometer (TDR) is
that it will not ____.
Answer:
wiring diagram or wiring legend yellow insulation green or green with yellow stripe pinpoint the
location of a short or open circuit at termination points box crimper 18 inches The length of wire runs
