QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS 100%
CORRECT RATED A+
Thermocouples turn _______ energy into _________ energy -ANSWER ✔✔ heat,
electrical
If you have a 240v circuit with 27 amps, what would the resistance be? -ANSWER
✔✔ 8.88 ohms
Capacitance is measured in _____. -ANSWER ✔✔ Microfarads
Which of the following is NOT a precaution to follow in the event of a propane
release or leak? -ANSWER ✔✔ return to gather info as soon as possible
What is the name of the OSHA standard to disable an electrical circuit and prevent
others from restoring it while you are working on the appliance? -ANSWER ✔✔
Lockout/tagout
Which device limits the gas flow to a predetermined propane input rate at the
burner? -ANSWER ✔✔ Orfice
Which device regulates the gas pressure to supply a constant pressure of propane at
the burners? -ANSWER ✔✔ Gas control valve
Which safety device shut down the appliance if the temperature is too high? -
ANSWER ✔✔Limit switch
Which device converts the power in a circuit from one voltage to another? -
ANSWER ✔✔Transformer
Source -ANSWER ✔✔The electrical supply for a circuit
Load -ANSWER ✔✔An electrical device that uses electricity to create heat,
motion, light sound, or some other form of useful work
Wire -ANSWER ✔✔A metal conductor of electricity
, Switch -ANSWER ✔✔A device to start or stop the flow of electricity in an
electrical circuit
Short circuit -ANSWER ✔✔An electrical circuit in which a wire or other
conductor is bypassing the load, so the current flows from the source through the
circuit in back to the source without going through a load
Open circuit -ANSWER ✔✔A circuit that has a brake in it so that the current
cannot flow through it
Current -ANSWER ✔✔The flow of electrons in an electrical circuit
Voltage -ANSWER ✔✔Electro motive force that moves electrical current through
a conductor. It is the amount of pressure difference between points in an electrical
circuit.
Resistance -ANSWER ✔✔The opposition to the flow of electrical current in an
electrical circuit
Alternating current -ANSWER ✔✔An electrical current changing regularly from
One Direction to the opposite direction
Direct current -ANSWER ✔✔Electric current going in only One Direction
Which of the following situation could potentially result in a shock when
troubleshooting an electrical circuit? -ANSWER ✔✔All of the above
If I load is not operating and you want to determine whether the load is receiving,
the electricity required for it to operate, you would measure which of the following
: volts, ohms, amps -ANSWER ✔✔Ohms
Open Measure and Continuity, the red meat or lead, should be connected, to which
of the following input jacks? -ANSWER ✔✔V or omega symbol
To prevent a short circuit, when measuring voltage, be sure you do which of the
following -ANSWER ✔✔Ensure that the tips of the test probably do not touch
each other
