Question #1
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A . 100 kHz
- B . 10 kHz
- C . 1000 Hz
- D . 100 Hz
Correct Answer: A
A
Explanation:
Frequency is the inverse of period, so to calculate the frequency of a signal with a period of 10 microseconds, you would divide 1 by the period, which is equal to 100 kHz.

Question #6
True or False: Fuel availability generally dictates the type of standby generator selected
- A . True
- B . False
Correct Answer: A
A
Explanation:
Fuel availability generally dictates the type of standby generator selected as different types of generators use different types of fuel. For example, gasoline generators are typically used in residential or small commercial applications, while diesel generators are usually used in larger industrial and commercial applications. Propane or natural gas generators may also be used, depending on the availability of fuel sources.

Question #8
Which one of the following controls the voltage produced at the output of the alternator?
- A . Voltage Meter
- B . Voltage Stabilizer
- C . Voltage Regulator
- D . Voltage Backup Device
Correct Answer: C
C
Explanation:
A voltage regulator controls the voltage produced at the output of the alternator. It’s a device that maintains the output voltage of an alternating current (AC) power source within a safe range. The voltage regulator compares the actual output voltage to the desired voltage level and adjusts the voltage accordingly.
Voltage Meter, Voltage Stabilizer, and Voltage Backup Device are not devices that control the voltage produced at the output of the alternator. They are different types of equipment and have different functions.
A voltage meter is a device used to measure the voltage in an electrical circuit. A voltage stabilizer is an electronic device that maintains a constant voltage level. A voltage backup device is a device that provides temporary backup power in case of an electrical outage.
