Sample Practice Test Questions
Which of the following is not a function of a car battery?
acts as a supplemental source of energy to moderate engine performance
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.
This circuit diagram represents a(n):
series circuit
A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.
In metals, increasing the temperature typically _____________ conductivity.
decreases
All conductors have resistance and the amount of resistance varies with the element. Metals exhibit increased resistance (and, therefore, lower conductivity) as their temperature increases.
The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.
series
A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.
What part of the brain is responsible for the major senses (thinking, hearing, seeing)?
cerebrum
The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).
A factor is a positive __________ that divides evenly into a given number.
integer
A factor is a positive integer that divides evenly into a given number. For example, the factors of 8 are 1, 2, 4, and 8.
The ignition coil is a(n):
step-up transformer
The ignition coil steps up the 12 volts available from the battery or alternator to a voltage of 30,000 or more volts at the spark plug. Converting a lower voltage input into a higher voltage output makes the ignition coil a step-up transformer.
An object's resistance to changes in direction is known as:
inertia
The more mass a substance has the more force is required to move it or to change its direction. This resistance to changes in direction is known as inertia.
