Automobile Part 1 Electrical System
Your car's electrical system consists of the battery, starter and alternator. The battery provides juice to the starter. Then, the alternator gives that battery the energy it needs to power your car. The part one quiz below is aimed at helping you learn more about the electrical system. Give it a try!
Questions and Answers
- 1.
What part of a car holds the electricity?
- A.
Alternator
- B.
Generator
- C.
Battery
- D.
Solenoid
- E.
Voltage regulator
Correct Answer
C. BatteryExplanation
The battery is the part of a car that holds the electricity. It stores electrical energy and provides power to start the engine and operate the electrical systems of the car. The alternator and generator are responsible for generating electricity to recharge the battery while the car is running. The solenoid is an electromagnetic switch that controls the flow of electricity. The voltage regulator ensures that the electrical system receives a consistent and regulated voltage from the battery.Rate this question:

The battery is made of lead, water and
- A.
Paint
- B.
Battery fluid
- C.
Gasoline
- D.
Sulfuric acid
Correct Answer
D. Sulfuric acidExplanation
Sulfuric acid is commonly used in batteries as an electrolyte. It helps in facilitating the flow of electric current between the battery's electrodes. Sulfuric acid is highly corrosive and can react with the lead plates in the battery to produce lead sulfate, which is crucial for the battery's operation. Water is also present in the battery to dilute the sulfuric acid and maintain the desired concentration. Paint, gasoline, and battery fluid are not typically found in batteries and do not serve the same purpose as sulfuric acid.Rate this question:

Where does the current go when the key is turned?
- A.
To the battery
- B.
To the starter
- C.
To the brakes
- D.
To the engine
- E.
To the alternater
Correct Answer
B. To the starterExplanation
When the key is turned, the current flows to the starter. The starter is responsible for initiating the engine's combustion process by turning the engine's flywheel. This action allows the engine to start running. Therefore, the current is directed to the starter to power it and start the engine.Rate this question:

What part of the electrical system keeps the battery charged?
- A.
The engine
- B.
The brakes
- C.
The alternator
- D.
The battery cables
- E.
The starter
Correct Answer
C. The alternatorExplanation
The alternator is responsible for keeping the battery charged in the electrical system. It converts mechanical energy from the engine into electrical energy, which is then used to charge the battery and power the electrical components of the vehicle. The alternator also regulates the voltage to ensure that the battery is not overcharged or undercharged.Rate this question:

What part keeps the battery from charging too much?
- A.
The voltage regulator
- B.
The lead
- C.
The cables
- D.
Fuse
- E.
Flux capacitor
Correct Answer
A. The voltage regulatorExplanation
The voltage regulator is responsible for keeping the battery from charging too much. It regulates the amount of voltage that is sent to the battery, ensuring that it does not exceed its maximum capacity. By controlling the charging process, the voltage regulator helps to prevent overcharging, which can damage the battery and reduce its lifespan.Rate this question:

What is ONE easy thing you can check for in your car to make sure the electrical system in in good shape?
- A.
The battery charge
- B.
Corrosion
- C.
Alternator
Correct Answer
B. CorrosionExplanation
One easy thing you can check for in your car to make sure the electrical system is in good shape is corrosion. Corrosion can occur on the battery terminals and cables, causing poor electrical connections and potentially leading to issues with starting the car or running electrical components. By regularly checking for and cleaning any corrosion, you can ensure that the electrical system is functioning properly and prevent any potential problems.Rate this question:

What part connects the engine to the alternator to make it turn when the engine turns.
- A.
Gears
- B.
V-belt
Correct Answer
B. V-beltExplanation
A v-belt is used to connect the engine to the alternator and allows it to turn when the engine turns. V-belts are flexible and can transmit power efficiently between the two components. They have a V-shaped cross-section that fits into grooves on the pulleys of the engine and alternator, creating friction and enabling the transfer of rotational motion. This connection ensures that the alternator is driven by the engine, allowing it to generate electricity and charge the battery.Rate this question:
