Which one of the following controls the voltage produced at the output of the alternator?
- A. Voltage Stabilizer
- B. Voltage Backup Device
- C. Voltage Regulator
- D. Voltage Meter
Answer: C
Explanation:
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.
NEW QUESTION 20
Every air distribution system has a ____________ system and a _________ system
- A. Maintenance, Regulation
- B. Supply, Reverse
- C. Supply, Release
- D. Supply, Return
Answer: D
Explanation:
Explanation
Every air distribution system has a supply system, which delivers conditioned air to the space, and a return system, which collects the air from the space and returns it to the air handling unit. The return system is responsible for providing the necessary negative pressure in the space to ensure proper air circulation.
NEW QUESTION 21
Which type of power can be a source available to the data center that takes over the function of supplying when utility power is unavailable?
- A. Active
- B. Alternate
- C. Standby
- D. Passive
Answer: C
Explanation:
Explanation
Standby power, also known as backup power, is a type of power that can be a source available to the data center that takes over the function of supplying when utility power is unavailable. Standby power systems are designed to provide power to critical loads in the event of a power outage, and can include generators, uninterruptible power supplies (UPS), and batteries. Standby power systems can be used to provide power to the data center for a short period of time, such as a few hours or days, until utility power is restored.
Passive, Active and Alternate are not specific type of power sources used in data center. They are terms used in different context and have different meaning.
NEW QUESTION 22
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 10 kHz
- B. 100 kHz
- C. 100 Hz
- D. 1000 Hz
Answer: B
Explanation:
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.
NEW QUESTION 23
