질문 # 20
Which one of the following uses sensors such as laser beams or touch sensor?
정답：A
설명：
Explanation
Alarms are physical security devices that use sensors such as laser beams or touch sensors to detect movement or intrusion. These devices are used to alert the user of any unauthorized activity in the area. Alarms can also be used in combination with CCTV cameras to provide a comprehensive security system.
질문 # 21
Which component protects electrical equipment from overloads or short circuits?
정답：B
질문 # 22
For which one of these processes is Direct Current essential, and will not work with alternating current?
정답：D
설명：
Explanation
Direct Current (DC) is essential for the process of electrolysis. Electrolysis is the process of breaking down a compound using an electric current. The electric current causes ions to move, which results in a chemical reaction that breaks down the compound. In order for electrolysis to work, a direct current is required, as the ions must flow in one direction. Alternating Current (AC) changes direction and would not provide a consistent flow of ions.
Heating, lighting, and turning a motor can be done by either DC or AC. Heating can be done by passing an electric current through a heating element, which can be powered by either DC or AC. Lighting can be done by passing an electric current through a light bulb, which can be powered by either DC or AC. A motor can be powered by either DC or AC, but the type of motor and the application will determine which type of current is more suitable.
질문 # 23
Every air distribution system has a ____________ system and a _________ system
정답：A
설명：
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.
질문 # 24
AC is more easily distributed than DC. This is because:
정답：A
설명：
Explanation
AC can be transformed from a low voltage to a high voltage and back again with a transformer, while DC cannot. This makes it easier to distribute AC electricity over long distances and is why it is used more widely than DC electricity. A and B are also true, as wires carrying AC can be bare and don't need to be totally insulated. Wires have less resistance when carrying AC electricity, which is why it is more efficient than DC.
