B)Most vehicles have two horns wired in parallel to each other and in series with the switch.
C)Pressing on the horn button closes a circuit to activate the horn capacitor.
D)The horn switch in the steering wheel is either a single or a multiple button-type switch.

Question 5

B)Taillights
C)Terminals
D)Brake lights

Question 6

Which of the following is the LEAST-Likely component of the windshield wiper motor?

A)Transmission housing
B)Solenoid
C)Cam rider
D)Armature

Question 7

Conventional incandescent light bulbs, often called lamps, have filaments that electricity flows through.

Question 8

Sealed-beam headlights have an inner glass or plastic reflector surface that is sprayed with an aluminum reflective material.

Question 9

Cables are protective devices designed to melt when the flow of current becomes too high for the wiring or loads in the circuit.

Question 10

All of the following statements are true EXCEPT:

A)a typical wiper motor has either two or three speeds.
B)a typical permanent magnet motor has three brushes, one of which is a common ground.
C)intermittent wipers allow the driver to vary the time interval a wiper sweeps across the windshield during foggy or misty conditions.
D)electromagnet wiper motors have four brushes on the armature.

Question 11

All of the following statements are true EXCEPT:

A)in fiber optics, light can be transmitted through a special plastic called polymethacrylate.
B)in some vehicles, fiber-optic strands illuminate an indicator on top of a fender when a turn signal flashes.
C)imported cars and some later-model domestics often use five bulbs for the brakes, turn signals, and running lights.
D)light-emitting diode (LED) lights or neon lights are sometimes used for headlights, brake lights, turn signals, and taillights.

Question 12

The ____________________ varies the amount of time it takes to recharge the capacitor, which triggers an electronic switch to begin wiper operation.

Question 13

Raising the turn signal mounted dimmer lever activates the high beams on most vehicles. This feature, called ____________________, works when the headlights are off as well as when the dimmer switch closes the circuit to the high beams.

A)rheostat
B)capacitor
C)armature
D)fuse

Question 15

____________________ are large wires that allow more electrical current to flow.

A)amps
B)candlepower
C)watts
D)volts

Question 18

Low-voltage wiring is called ____________________.
