Which of the following is not a function of a car battery?

51% Answer Correctly

acts as an electrical reservoir for excessive current

acts as a supplemental source of energy to moderate engine performance

delivers current to the ignition system to start the engine

delivers supplemental current when the alternator can't handle high electrical system loads


Solution

The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.


2

__________ are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

67% Answer Correctly

suspension springs

control arms

shock absorbers

ignition coils


Solution

Suspension springs are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

What is the function of the alternator?

59% Answer Correctly

provides AC power for the car's electrical components

replaces the electrical energy that the car draws from the battery

charges the battery when the car is not running

converts motion from the wheels into DC power


Solution

An automobile's electrical system runs on DC power and the bulk of that power is supplied by the battery. The alternator converts the motion of the rotor into AC power which is then fed through the rectifier to convert it to DC power that both the car and the battery can use.

66% Answer Correctly

base

shaft

hub

knuckle


Solution

The wheel hub is the mounting point for the wheel and tire assembly. The wheel hub can rotate while being held stable by the steering knuckle which applies the motion of the control arms to the wheels.
