    Direct current is electrical current which flows in one direction only

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Direct current is a type of electrical current that flows in one direction only. Unlike alternating current, which constantly changes direction, direct current maintains a constant flow in a single direction. This is typically achieved through the use of batteries or power supplies that convert alternating current into direct current. Direct current is commonly used in electronic devices, such as computers, televisions, and mobile phones, as well as in certain industrial applications. Therefore, the statement "Direct current is electrical current which flows in one direction only" is true.

  • 21. 

    Which switches must indicate whether they are in the open or closed position?

    • General-use switches

    • Motor-circuit switches

    • Circuit breakers

    • All of these

    Correct Answer
    A. All of these
    Explanation
    All of these switches must indicate whether they are in the open or closed position. This is because it is important to know the status of the switches for safety and operational purposes. In general-use switches, it allows users to control the flow of electricity in a circuit. In motor-circuit switches, it helps in controlling the power supply to motors. Circuit breakers also need to indicate their position to show whether the circuit is open or closed, and to protect against overloads or short circuits. Therefore, all of these switches should have indicators to show their open or closed position.

    Ground-fault circuit interrupters for swimming pools are permitted in a panel board that contains circuits protected by other than ground-fault circuit interrupters?(18-27-680.5.)

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Ground-fault circuit interrupters (GFCIs) are allowed to be installed in a panel board that also contains circuits protected by devices other than GFCIs. This means that even if some circuits in the panel board are protected by different types of circuit interrupters, it is still permissible to have GFCIs installed for swimming pools. This is important for safety purposes as GFCIs are specifically designed to protect against electrical shock hazards in wet environments like swimming pools. Therefore, the statement is true.

    • The dc voltage must not be generated at the level required by the load.

    • The dc voltage must be generated at the level required by the load.

    Correct Answer
    A. The dc voltage must be generated at the level required by the load.
    Explanation
    A disadvantage of a direct-current system with respect to supply voltage is that the dc voltage must be generated at the level required by the load. This means that the voltage needs to be adjusted and regulated to match the specific requirements of the load, which can be a more complex and costly process compared to an alternating-current system where the voltage is easily adjustable through transformers.

    Any person who knowingly violates a stop work order is subject to a a fine of not less than $400, nor more than $1,000 for the first offense? (13-12-080)

    • True

    • False

    Correct Answer
    A. True
    Explanation
    According to section 13-12-080, any person who knowingly violates a stop work order is subject to a fine of not less than $400, nor more than $1,000 for the first offense. Therefore, the statement "Any person who knowingly violates a stop work order is subject to a fine of not less than $400, nor more than $1,000 for the first offense" is true.

    Other than purposes listed in Section 18-27-400.7, flexible cords and cables may run through holes in walls?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Flexible cords and cables may not run through holes in walls unless they are being used for one of the purposes listed in Section 18-27-400.7. This means that unless the cords and cables are being used for specific applications such as connecting equipment, temporary wiring, or other approved uses, they are not allowed to pass through holes in walls. Therefore, the correct answer is False.

    A motor draws 83 amps at a voltage of 460 with a feeder ft. length of 190. The copper wire (75 degree C) size desired is #3, Which minimum size copper wire is permissible by code to use?

    • 3

    • 2

    • 1

    Correct Answer
    A. 3
    Explanation
    The correct answer is 3. According to the given information, the motor draws 83 amps at a voltage of 460, and the desired copper wire size is #3. The National Electrical Code (NEC) specifies the minimum wire size based on the current carrying capacity. Since the motor draws 83 amps, the #3 copper wire is permissible as it can handle that current load. Therefore, the minimum size copper wire permissible by code to use is #3.
