Question 1

Technician A says dash lights are an excellent example of a series-parallel circuit. Technician B says a rheostat is used to control the turn signal lights and the emergency flashers. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Dash lights are indeed an example of a series-parallel circuit, allowing them to operate independently and together, while a rheostat is typically used to adjust the brightness of dash lights, not to control turn signal lights or emergency flashers.

cranking

Question 3

The AWG assigns a _____________ number to an electrical wire based on the wire diameter.

Question 4

Technician A says a battery that has been heavily discharged should be recharged using a slow trickle charge cycle for approximately 30 minutes and then finish with a 10 minute fast charge. Technician B says a high-voltage hybrid battery should only be charged using vehicle specific equipment that is manufactured by the car manufacturer. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

The answer of Technician A says a battery that has...

Question 5

Technician A says another name for a digital multi-meter (DMM) is DVOM. Technician B says a test light is equally effective to use for testing non-functioning circuits. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Technician A is correct. A DMM is also known as a digital volt-ohm meter (DVOM). Technician B is incorrect. A test light can only test for the presence of voltage and cannot accurately determine if a circuit is functioning properly.

Question 6

One non-functioning component in a series circuit will cause the entire circuit to not function.

Accepted Answer

In a series circuit, the current can only flow in one path, so if there is a break or non-functioning component in that path, the current cannot flow and the entire circuit will not function.

Question 7

Any module within ___________ inches of a welding site should be removed to avoid damaging it.

Accepted Answer

The answer of Any module within ___________ inches of a...

Question 8

Kirchhoff's law states that the sum of all voltage drops in a circuit plus the source voltage equals zero.

Accepted Answer

The answer of Kirchhoff's law states that the sum of...

Question 9

Technician A says a switch is considered a circuit control device. Technician B says a relay is often used when a high amount of voltage must be reduced to a low voltage function. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Technician A is correct because a switch is indeed considered a circuit control device, as it can open or close a circuit, thereby controlling the flow of electricity. Technician B is incorrect because a relay's primary function is not to reduce voltage but to allow a low-power circuit to control one or more higher power circuits.

Question 10

A fuse and circuit breaker are circuit protection devices used by auto manufacturers to protect the ________________ .

Accepted Answer

The answer of A fuse and circuit breaker are circuit...

Question 11

Technician A says a state of charge test can be done on a battery by placing the DVOM leads on the positive post of the battery and taking a reading. Technician B says a battery stores energy in electrical form. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

A state of charge test requires measuring the voltage across both the positive and negative terminals, not just the positive post. Additionally, a battery stores energy in chemical form, not electrical form.

Question 12

Which of the following would not be considered an external light circuit?
A) Headlamp
B) Map light
C) Stop lamp
D) Backup lamp

Accepted Answer

A, C, and D are all lights on the exterior of the vehicle that are used for safety and visibility purposes. The map light is typically an interior light for providing illumination for reading or finding items within the vehicle, and is not part of the external light circuit.

Question 13

Technician A says an open is any disruption in the circuit and may be a break in the wire, a switch or disconnected light. Technician B says a short occurs when there is an unwanted path for current to flow. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Technician A is correct in stating that an open is any disruption in the circuit which may be caused by a break in the wire, a switch, or a disconnected light. Technician B is correct in saying that a short occurs when there is an unwanted path for current to flow. Therefore, both technicians are correct, and the best answer is C - Both A and B.

Question 14

A fully charged automotive battery will measure ____________ volts.

Accepted Answer

The answer of A fully charged automotive battery will measure...

Question 15

Technician A says a voltage drop test is an excellent means of checking circuits for opens or resistance. Technician B says to check for the source of unwanted voltage drop in a circuit, one need only place the contacts at the point where the current leaves the source voltage and the other lead at the point where it returns. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Technician A is correct that a voltage drop test is an excellent means of checking circuits for opens or resistance. Technician B is incorrect because to check for the source of unwanted voltage drop in a circuit, one needs to place the contact at the point where the current enters the circuit and the other lead at the point where the voltage drops, not where it returns.

Question 16

Ohm's law defines the relationship between voltage, current and resistance.

Accepted Answer

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them.

Question 17

A short occurs any time there is an open in a circuit.

Accepted Answer

A short occurs when there is an unintended path of low resistance which allows an excessive flow of current, bypassing the normal load, not an open in a circuit. An open circuit is when the path for electrical current is interrupted or broken, preventing current from flowing at all.

Question 18

Technician A says amperage is the amount of electron flow. Technician B says another name for electron flow is current flow. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Technician A is correct that amperage is the amount of electron flow. Technician B is correct that another name for electron flow is current flow. Therefore, both technicians are correct.

Question 19

Technician A says dash lights are an excellent example of a series-parallel circuit. Technician B says a rheostat is used to control the turn signal lights and the emergency flashers. Who is correct?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

Dash lights are indeed an example of a series-parallel circuit, allowing for individual control while being part of a larger circuit. A rheostat is typically used to adjust the brightness of dash lights, not to control turn signal lights or emergency flashers.

Question 20

All wiring repairs are made in the same fashion.

Accepted Answer

Wiring repairs can vary depending on the nature and location of the issue. Some repairs may involve replacing entire sections of wiring, while others may only require splicing and reconnecting wires. Additionally, the tools and techniques used for different types of wiring and electrical systems can vary.
