Sample Practice Test Questions

Electronics Information

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.

Mechanical Comprehension
lengthen the ramp

Which of the following will increase the mechanical advantage of this inclined plane?

lengthen the ramp

The mechanical advantage (MA) of an inclined plane is the effort distance divided by the resistance distance. In order to increase mechanical advantage, this ratio must increase which means making the effort distance longer and this can be accomplished by lengthening the length of the ramp.

Word Knowledge
Gravity most nearly means:
seriousness
Importance, significance.
Arithmetic Reasoning

What is \( \frac{4}{6} \) ÷ \( \frac{4}{8} \)?

1\(\frac{1}{3}\)

To divide fractions, invert the second fraction and then multiply:

\( \frac{4}{6} \) ÷ \( \frac{4}{8} \) = \( \frac{4}{6} \) x \( \frac{8}{4} \)

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{4}{6} \) x \( \frac{8}{4} \) = \( \frac{4 x 8}{6 x 4} \) = \( \frac{32}{24} \) = 1\(\frac{1}{3}\)

General Science

The crust and upper mantle of the earth is called the:

lithosphere

The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).

Word Knowledge
Fidelity most nearly means:
loyalty
State of being faithful.
Electronics Information

The hertz is a unit of measurement for:

frequency

The hertz is a unit of measurement for frequency.

Shop Information

Which of the following would provide the most accurate measure of the diameter of a solid cylinder?

outside micrometer

Micrometers provide accuracy to the thousandths of an inch and come in outside and inside varieties. An outside micrometer is used to measure outside thickness, such as the diameter of a bolt, while an inside micrometer is used to measure the inside dimension of an object, such as the diameter of the hole of a nut or the width of a channel.

Word Knowledge
Trevor decided to freeze the surplus chili for next week's tailgate party.
surfeit
Excess.
Math Knowledge

What is the area of a circle with a radius of 2?

The formula for area is πr2:

a = πr2
a = π(22)
a = 4π
