Complete Solutions
A potentiometer, a three-wire variable resistor is used in which type of sensor? -
ANSWER-Throttle Position
A technician is diagnosing an interior light that will not turn off. The technician removes
the vehicle's carpet and finds a wire whose insulation has rubbed though , causing the
wire's conductor to touch the metal body of the vehicle. When the suspect wire is lifted
away from the body of the vehicle, the light turns off. This is an example of
________________. - ANSWER-a short to ground
An electrical conductor is an element with ___________ electrons in its outer orbit -
ANSWER-Less than 4
As temperature increases - ANSWER-Resistance increases
Carbon and Silicon are examples of ___ - ANSWER-Semiconductors
Creating electricity by exerting a force on a crystal is called ___ - ANSWER-
Piezoelectricity
Heavy corrosion is found on the terminals of an electrical connector. Technician A says
the corrosion cases high resistance in the electrical circuits that pass through the
connector. Technician B says the corrosion causes opens in the circuits that pass
through the connector. Who is correct? - ANSWER-tech a
Like charges ________ - ANSWER-Repel
Tech A says that a two-wire variable resistor is called a rheostat. Tech B says that a
three wire variable resistor is called a potentiometer. Which tech is correct? - ANSWER-
Neither
The _________ is a unit of electrical pressure - ANSWER-Volt
The fact that voltage can be created by exerting force on a crystal is used in which type
of sensor? - ANSWER-Knock Senor
What are 5 sources of electricity? - ANSWER-Friction, heat, light, pressure, chemical,
and magnetism.
What are ampere, volt, and ohm? - ANSWER-Ampere is a unit used to measure current
flow, volt is the unit of measurement for electrical pressure, and ohms is the unit of
measurement of resistance to the flow of current through a conductor.
