質問 # 20
For which one of these processes is Direct Current essential, and will not work with alternating current?
- A. Lighting
- B. Heating
- C. Turning a motor
- D. Electrolysis
正解：D
解説：
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.

質問 # 27
Which one of the following describes the amount of resistance electricity encounters?
- A. Ampere
- B. Volts
- C. Ohm
- D. Watts
正解：C
解説：
Explanation
Ohm () describes the amount of resistance electricity encounters. It is one of the base units of the International System of Units (SI), and is defined as the amount of resistance that a conductor has when a force of one volt is applied across it. Ohms are used to measure the electrical resistance of a circuit, and can be used to determine the power of a circuit or the amount of current flowing through it.
質問 # 28
What are the two main applications for ac (alternate current)?
- A. electric, magnetic
- B. direct, pulsating
- C. power, information
- D. static, dynamic
正解：C
解説：
Explanation
The two main applications for AC (alternate current) are power and information. AC is used to generate and transfer power to electrical devices, and is also used to carry information signals in telecommunications.
質問 # 29
Which one of the following is an advantage of using Natural Gas?
- A. Minimum carbon build up
- B. More exhaust able
- C. Maximum carbon build up
- D. Tends to cost more
正解：A
解説：
Explanation
The main advantage of using natural gas is that it tends to produce fewer carbon emissions than other fossil fuels, such as coal or oil. Natural gas combustion produces less carbon dioxide and other pollutants than other fuels, making it a cleaner and more renewable source of energy. Additionally, natural gas costs less than other fuels, making it a more cost-effective option.
質問 # 30
AC is more easily distributed than DC. This is because:
- A. Wires have less resistance if they are carrying AC
- B. AC can be transmitted using lighter wires.
- C. DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.
- D. AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.
正解：D
解説：
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.
質問 # 31
Which one of the following is a Physical Security Identification Method?
- A. Sound
- B. Voice
- C. Batch ID
- D. Expression
正解：B
解説：
Explanation
Voice identification is a physical security identification method that uses the sound of an individual's voice to identify them. This method is often used in combination with other identification methods, such as biometric scans, to provide a more secure form of authentication. Voice identification is used in a variety of situations, such as when accessing a secure facility or when making financial transactions.

質問 # 33
__________ represents the maximum power cable of being drawn by the equipment.
- A. VA rating
- B. Star rating
- C. Power rating
- D. Grade rating
正解：C
解説：
Explanation
Power rating represents the maximum power that can be drawn by the equipment. It is usually measured in watts (W) or kilowatts (kW) and represents the maximum amount of power that the equipment can consume without causing damage to the device or the power source.
VA rating (Volt-Ampere rating) is a measure of the apparent power in a circuit, which is the product of the voltage and current in the circuit. It is often used to describe the power handling capability of electronic devices and equipment.
Star rating is a rating system used to indicate the energy efficiency of electrical devices and equipment. The rating ranges from 1 to 5 stars, with 5 stars indicating the most energy-efficient device.
Grade rating is a rating system used to indicate the quality of electrical devices and equipment. It is used in different industry and can indicate the quality of electronic component and material used in equipment.
