  • 2. 

    An ion is an atom in which the number of electrons and the number of protons are not equal.

    • A. True

    • B. False

    Correct Answer
    A. A. True
    Explanation
    An ion is formed when an atom gains or loses electrons, resulting in an unequal number of electrons and protons. This imbalance creates a positive or negative charge, making the atom an ion. Therefore, the statement that an ion is an atom in which the number of electrons and protons are not equal is true.

    If I = 6 amps and R = 2 ohms then E = _________ volts.

    • A. 8

    • B. 12

    • C. 3

    • D. not enough information

    Correct Answer
    A. B. 12
    Explanation
    Given the values of current (I) and resistance (R), we can use Ohm's Law (E = I * R) to calculate the voltage (E). In this case, the current is 6 amps and the resistance is 2 ohms. Therefore, E = 6 * 2 = 12 volts.

    Microwaves travel in a straight line and require air as a medium.

    • A. True

    • B. False

    Correct Answer
    A. B. False
    Explanation
    Microwaves do not require air as a medium to travel. They can travel through a vacuum, which means they can travel in space where there is no air. Therefore, the statement that microwaves require air as a medium is false.

    Rate this question:

  • 5. 

    Photoelectric Beams are _________ sensors.

    • A. active

    • B. passive

    • C. dormant

    • D. useless

    Correct Answer
    A. A. active
    Explanation
    Photoelectric beams are active sensors because they emit a beam of light and detect if the beam is interrupted or blocked. They actively send out a signal and actively receive the signal back to determine if there is any obstruction. Passive sensors, on the other hand, rely on detecting changes in the environment without actively emitting any signal. Dormant and useless are not applicable terms for describing photoelectric beams.

  • 6. 

    Resistors are required at the end of the line in order to _________.

    • A. restrict current

    • B. identify where the wire runs

    • C. supervise the circuit

    • D. adjust for over or undersized wiring

    Correct Answer
    A. C. supervise the circuit
    Explanation
    Resistors are not typically used to supervise a circuit. They are used to restrict current flow in a circuit, adjust for over or undersized wiring, or in some cases, to identify where the wire runs. Therefore, the given answer is not correct.

    Rate this question:

  • 7. 

    Orange, Orange, Black — A resistor with the first three bands in this order equals what value?

    • A. 13 ohms

    • B. 33 ohms

    • C. 3,600 ohms

    • D. 4.2 kiliohms

    Correct Answer
    A. B. 33 ohms
    Explanation
    The colors of the resistor bands are used to determine the resistance value. In this case, the first band is orange, which represents the digit 3. The second band is also orange, representing the digit 3 again. The third band is black, which represents a multiplier of 1. Therefore, the resistor has a value of 33 ohms.

    Rate this question:

  • 8. 

    A train horn coming toward you getting louder and then getting lower as it passes you is an example of _________.

    • A. Kirschoff’s Law

    • B. subsonic wave compression

    • C. Doppler Shift

    • D. Fresnel compression

    Correct Answer
    A. C. Doppler Shift
    Explanation
    The phenomenon described in the question is known as the Doppler Shift. The Doppler Shift occurs when there is a change in frequency or pitch of a sound wave due to the relative motion between the source of the sound and the observer. In this case, as the train approaches the observer, the sound waves are compressed, resulting in a higher frequency and a louder sound. As the train passes by and moves away, the sound waves are stretched, resulting in a lower frequency and a quieter sound. Therefore, the correct answer is c. Doppler Shift.

    Glass reflects but does not absorb microwave energy.

    • A. True

    • B. False

    Correct Answer
    A. B. False
    Explanation
    Glass does not reflect or absorb microwave energy. Instead, it allows microwaves to pass through it. This is why microwave ovens use glass doors, so that you can see inside while the microwaves stay contained. Therefore, the statement that glass reflects but does not absorb microwave energy is incorrect.

    What is the sum of the following figures:  0.75 amps + 200 milliamps + 1.5 amps + 1,000,000 microamps

    • A. 3.5 amps

    • B. 4,250 milliamps

    • C. 3.45 amps

    • D. 2,750 milliamps

    Correct Answer
    A. C. 3.45 amps
    Explanation
    The sum of the figures given is 0.75 amps + 0.2 amps + 1.5 amps + 1 amp, which equals 3.45 amps.

    A material with few free electrons is called a(n) _________.

    • A. conductor

    • B. ion

    • C. isolator

    • D. insulator

    Correct Answer
    A. A. conductor
    Explanation
    A material with few free electrons is called a conductor. Conductors are materials that allow the flow of electric current due to the presence of free electrons that can move easily through the material. These materials typically have a high electrical conductivity and are used in applications where the transfer of electricity is desired, such as in wires and cables.

    A _________ is a device that converts energy from one form to another.

    • A. transceiver

    • B. transformer

    • C. transducer

    • D. transmitter

    Correct Answer
    A. C. transducer
    Explanation
    A transducer is a device that converts energy from one form to another. It can take different forms depending on the type of energy being converted. For example, a microphone is a transducer that converts sound energy into electrical energy, while a solar panel is a transducer that converts sunlight into electrical energy. Therefore, a transducer is the correct answer as it encompasses the broad concept of energy conversion in various forms.

    The formula to determine the value of a circuit with two parallel resistors is:

    • A. R1+R2/R1*R2

    • B. RT

    • C. (R1*R2)2/R1+R2

    • D. R1*R2/R1+R2

    Correct Answer
    A. D. R1*R2/R1+R2
    Explanation
    The correct answer is d. R1*R2/R1+R2. This formula is used to calculate the total resistance of a circuit with two parallel resistors. In a parallel circuit, the total resistance is given by the reciprocal of the sum of the reciprocals of the individual resistances. The formula R1*R2/R1+R2 simplifies this calculation by multiplying the two resistances and dividing the result by their sum.
