CORRECT ANSWERS 2025/2026
_____ is achieved when an electrical circuit has a continuous and uninterrupted electrical
connection and is thereby capable of conducting current and working as designed. - Correct
answercontinuity
_____ solder is used on electrical connections because it is much ____ likely to corrode the
metals than _____. - Correct answerrosin flux; less; acid flux
"ground" is a term used by technicians to indicate the portion of the circuit that returns current
flow to the negative side of the battery - Correct answertrue
a good time tp check batteries is ______, - Correct answerduring oil changes and in the fall
, A load test is testing the battery's ability to produce the high starting current, while maintaining
enough voltage to operate the ignition and electronic control systems. - Correct answertrue
A sensor essentially converts an electrical signal into mechanical actions that can be read by the
microprocessors in the control units. - Correct answerfalse
According to Ohm's law, if 12 volts are applied to a circuit that has 12 ohms of resistance, the
resulting current flow will be ____. - Correct answer1 amp
all these statements are true about protection devices EXCEPT: - Correct answeryou should
always replace blown fuses with a fuse of a higher amp rating
Alternating current: - Correct answermoves back and forth
Always ensure that power is connected before connecting ammeters, and ensure that the test
instrument is capable of measuring the expected current draw. - Correct answerfalse
amps are the result of both the voltage and resistance - Correct answertrue
An application of Zener diodes in vehicles is the: - Correct answervoltage regulator
An oscilloscope provides a graph of voltage values over a time period, typically called a
___________, and displays them on a screen. - Correct answerwaveform
As hydrocarbons become _____________, the increased use of sophisticated electrical and
electronic systems in vehicles to improve efficiency and economy will continue into the future. -
Correct answerscarcer and more effective
As plate material becomes deposited in the bottom of the battery case, it eventually shorts out
the plates and renders that cell useless, which causes the battery to fail under load. - Correct
answertrue
