Questions and Answers
  • 1. 

    Define as the flow of electrons or electric current. It is an invisible form of energy that can be transformed into another form of energy like heat light and mechanical.

    • A.

      Electricity

    • B.

      Resistance

    • C.

      Proton

    • D.

      Electron

    Correct Answer
    A. Electricity
    Explanation
    Electricity is defined as the flow of electrons or electric current. It is an invisible form of energy that can be transformed into other forms of energy such as heat, light, and mechanical energy.

  • 2. 

    The negative charge component of an atom. It has the ability to flow.

    • A.

      Electricity

    • B.

      Resistance

    • C.

      Proton

    • D.

      Electron

    Correct Answer
    D. Electron
    Explanation
    An electron is the correct answer because it is a negatively charged particle that is found in the outer shells of atoms. It has the ability to move or flow, which is essential for the conduction of electricity.

    Rate this question:

  • 3. 

    The positive charge component of an atom. It had the ability to attract an electron.

    • A.

      Electricity

    • B.

      Resistance

    • C.

      Proton

    • D.

      Electron

    Correct Answer
    C. Proton
    Explanation
    A proton is a positively charged component of an atom. It has the ability to attract an electron, which is a negatively charged particle. In an atom, protons are located in the nucleus, while electrons orbit around the nucleus. This attraction between protons and electrons is what creates the electrical force that allows for the flow of electricity. Therefore, the correct answer is proton.

    Anything that occupies space and has mass. It can be a solid, liquid, or gas in the state.

    • A.

      Atom

    • B.

      Matter

    • C.

      Current

    • D.

      Voltage

    Correct Answer
    B. Matter
    Explanation
    Matter refers to anything that has mass and occupies space, whether it is a solid, liquid, or gas. It encompasses all physical substances and materials in the universe. Atoms, which are the basic building blocks of matter, are included in this definition. Therefore, matter is the correct answer because it aligns with the given definition.

    Rate this question:

  • 5. 

    The amount of pulling force that makes the electron flow. Also known as potential difference or EMF(electromotive force). The amount of voltage can be measured in volt (V).

    • A.

      Atom

    • B.

      Matter

    • C.

      Current

    • D.

      Voltage

    Correct Answer
    D. Voltage
    Explanation
    Voltage is the amount of potential difference or electromotive force (EMF) that is necessary to make the electrons flow. It is measured in volts (V). This explanation highlights the relationship between voltage and electron flow, as well as the unit in which voltage is measured.

    Rate this question:

  • 6. 

    The flow of electric charge is only in one direction.

    • A.

      AC

    • B.

      DC

    • C.

      BC

    • D.

      CC

    Correct Answer
    B. DC
    Explanation
    DC stands for Direct Current, which refers to the flow of electric charge in only one direction. Unlike AC (Alternating Current), which periodically changes direction, DC maintains a constant flow of electrons in a single path. This is commonly used in batteries and electronic devices that require a steady and unidirectional flow of electricity. Therefore, the given correct answer, DC, accurately describes the flow of electric charge in one direction.

    Rate this question:

  • 7. 

    The movement of electric charge periodically reverses direction.

    • A.

      AC

    • B.

      DC

    • C.

      BC

    • D.

      DC

    Correct Answer
    A. AC
    Explanation
    AC stands for alternating current, which is a type of electric current where the movement of electric charge periodically reverses direction. This means that the flow of electrons changes its polarity over time, oscillating back and forth. In contrast, DC (direct current) flows in only one direction. BC is not a recognized abbreviation in the context of electric currents. Therefore, the correct answer is AC.

    Rate this question:

  • 8. 

    Commonly represented by a bulb or any electrical component that consumes electricity.

    • A.

      Electricity

    • B.

      Supply

    • C.

      Switch

    • D.

      Load

    Correct Answer
    D. Load
    Explanation
    A load is commonly represented by a bulb or any electrical component that consumes electricity. In an electrical circuit, a load is the part that uses the electrical energy provided by the power source. It can be a device, appliance, or any other electrical component that converts electrical energy into another form, such as light, heat, or motion. The load is connected to the power source through wires and is responsible for drawing the necessary amount of current to perform its intended function.

    Rate this question:

  • 9. 

    Type of circuit that has an open path for current to flow. It means that the current cannot flow in an open circuit.

    • A.

      Load

    • B.

      Supply 

    • C.

      Open 

    • D.

      Closed 

    Correct Answer
    C. Open 
    Explanation
    An open circuit refers to a type of circuit that does not have a complete path for current to flow. In other words, the circuit is not closed, and therefore, current cannot flow through it. Unlike a closed circuit where current can flow continuously, an open circuit interrupts the flow of current, resulting in no electrical activity.

    Rate this question:

  • 10. 

    Materials that easily allow the flow of current.

    • A.

      Insulator

    • B.

      Conductor

    • C.

      AC

    • D.

      DC

    Correct Answer
    B. Conductor
    Explanation
    A conductor is a material that easily allows the flow of current. Unlike insulators, which inhibit the flow of electricity, conductors have a high number of free electrons that can move easily through the material. This property makes conductors ideal for transmitting electricity and is why materials like copper and aluminum are commonly used in electrical wiring.
