    Rate this question:

  • 3. 

    Connected to earth or to some conducting body that serves in place of the earth.

    • A.

      Voltage (of a circuit)

    • B.

      Watertight

    • C.

      Receptacle Outlet

    • D.

      Grounded

    Correct Answer
    D. Grounded
    Explanation
    Grounded refers to the state of being connected to the earth or to a conducting body that acts as the earth. Being grounded is important in electrical circuits as it helps to prevent electrical shocks and ensures the safety of the system. When a circuit is grounded, any excess electrical charge or fault current is directed safely into the ground, reducing the risk of damage or injury. This connection to the earth provides a reference point for voltage measurements and helps to stabilize the electrical system.

    Rate this question:

  • 4. 

    The conductors from the service point to the service disconnecting means.

    • A.

      Watt

    • B.

      Service Conductors

    • C.

      Grounded

    • D.

      Thermopile

    Correct Answer
    A. Watt
    Explanation
    The given statement refers to the conductors that connect the service point to the service disconnecting means. It does not mention anything about grounded or thermopile. The term "Watt" is not relevant to the given statement and seems to be unrelated. Therefore, the explanation for the correct answer "Watt" is not available.

    Rate this question:

  • 5. 

    An outlet where one or more receptacles are installed.

    • A.

      Approved

    • B.

      Receptacle Outlet

    • C.

      Watertight

    • D.

      Outlet

    Correct Answer
    B. Receptacle Outlet
    Explanation
    A receptacle outlet is an outlet where one or more receptacles are installed. Receptacles are the electrical devices that allow you to plug in and connect various appliances and devices. Therefore, a receptacle outlet is a specific type of outlet that has receptacles installed in it, allowing you to power and use multiple devices at once.

    Rate this question:

  • 6. 

    The greatest root-mean-square (effective) difference of potential between any two conductors of the circuit concerned.

    • A.

      Thermopile

    • B.

      Watt

    • C.

      Grounded

    • D.

      Voltage (of a circuit)

    Correct Answer
    D. Voltage (of a circuit)
    Explanation
    The correct answer is Voltage (of a circuit). Voltage refers to the potential difference between two points in a circuit. It represents the amount of electrical potential energy per unit charge. The root-mean-square difference of potential is a measure of the effective voltage in a circuit, taking into account both the magnitude and frequency of the voltage. Therefore, the greatest root-mean-square difference of potential between any two conductors in the circuit represents the highest voltage in the circuit.

    Rate this question:

  • 7. 

    More than one thermocouple connected together. The connections may be series, parallel, or both.

    • A.

      Thermocouple

    • B.

      Outlet

    • C.

      Thermopile

    • D.

      Approved

    Correct Answer
    C. Thermopile
    Explanation
    A thermopile is a device that consists of multiple thermocouples connected together in series or parallel, or both. When exposed to a temperature gradient, each thermocouple in the thermopile generates a small voltage. By connecting multiple thermocouples, the voltage output of the thermopile can be increased. This makes the thermopile suitable for applications that require higher voltage outputs, such as powering electronic devices or measuring temperature differentials. Therefore, the given answer "Thermopile" is the correct choice as it accurately describes the device formed by connecting multiple thermocouples together.

    Rate this question:

  • 8. 

    A device that responds to when the temperature rises at a rate exceeding a predetermined value.

    • A.

      Rate of Rise Detector

    • B.

      Watertight

    • C.

      Should

    • D.

      Thermopile

    Correct Answer
    A. Rate of Rise Detector
    Explanation
    A rate of rise detector is a device that is designed to respond when the temperature increases at a rate that surpasses a pre-determined value. This means that if the temperature rises too quickly, the rate of rise detector will be triggered and respond accordingly. It is commonly used in various applications where monitoring temperature changes is crucial, such as fire alarm systems or industrial processes. The rate of rise detector helps to ensure safety and prevent potential hazards by alerting users when the temperature rises rapidly.

    Rate this question:

  • 9. 

    Indicates a recommendation or that which is advised but not required.

      Voltage (of a circuit)

    • C.

      Should

    • D.

      Rate of Rised Detector

    Correct Answer
    C. Should
    Explanation
    The term "should" suggests a recommendation or advice, indicating that something is advisable or recommended but not mandatory. In the context of the given symbols, "should" implies that the action or condition represented by the symbol is not required, but it is suggested or recommended to follow or achieve a desired outcome.

    Rate this question:

  • 10. 

    A screw or a quick-connect device where a conductor(s) is intended to be connected.

    • A.

      Surge Suppressor

    • B.

      Thermopile

    • C.

      Watertight

    • D.

      Terminal

    Correct Answer
    D. Terminal
    Explanation
    A terminal is a screw or quick-connect device used to connect a conductor(s). It provides a secure and reliable connection point for electrical wires or components. Terminals are commonly used in electrical and electronic systems to facilitate the flow of electricity and ensure proper functioning of the circuit. They are designed to securely hold the conductor in place and prevent any accidental disconnection.
