Sample Practice Test Questions

Electronics Information

The farad is a unit of measurement for:

capacitance

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.

Word Knowledge
Demean most nearly means:
humble
To lower status.
General Science

In the food chain, consumers are classified as which of the following?

all of these

Most animals consume other organisms to survive. Consumers (heterotrophs) are divided into three types, primary, secondary, and tertiary, based on their place in the food chain.

Electronics Information

Which of the following is a characteristic of batteries connected in parallel?

total current equals the sum of the individual battery currents

You can multiply the voltage or the current supplied by individual batteries by connecting them together either in series or in parallel. The characteristics of batteries connected in parallel are that total voltage equals the average of the individual battery voltages, total current equals the sum of the individual battery currents, the positive terminal of one battery is connected to the positive terminal of the next, the negative terminal of one battery is connected to the negative terminal of the next, and two connections are made between each adjacent battery.

Word Knowledge
Grandiose most nearly means:
pretentious
With an affectation of grandeur.
Word Knowledge
Sarah thought George's ploy of borrowing her notes was a cowardly way to ask her out.
strategem
A contrived plan.
Word Knowledge
Revive most nearly means:
reanimate
To bring back to life.
Word Knowledge
Induce most nearly means:
incite
To influence or cause.
Electronics Information

You would measure the amount of current through a circuit with a(n):

ammeter

Current is the rate of flow of electrons per unit time and is measured in amperes (A). An ammeter is used to measure the electric current in a circuit.

Math Knowledge

Which of the following is not true about both rectangles and squares?

the lengths of all sides are equal

A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
