Electricity Quizzes & Trivia

Electricity can be defined as the flow of electric charge, but that's not enough. Do you really know how electricity is generated? And from where does it come? There are a number of questions unanswered. This quiz has been developed for students, researcher and learners to gain and test their knowledge about electrical circuits and components. So, let's try out the quiz. All the best!


Questions and Answers
  • 1. 

     What is the size/gauge house wire that most commonly found in houses/apartments for outlets and light switches (in rooms other than kitchen and bathroom)?

    • A.

      16 gauge

    • B.

      12 gauge

    • C.

      14 gauge

    • D.

      10 gauge

    You have a bad breaker in your panel box, so you go down to the hardware store and the guy (...or girl!) tells you that you can use any kind of breaker as long as it's the same amperage.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Most electrical breakers are interchangeable. That means some names like Murry and Bryant, you can put in a Crouse Hinds breaker, that name fits both. Names like Square D (including Square D "homeline"), Cutler Hammer, GE, and Federal Pacific are NOT interchangeable, and you can only put the same named breaker back in. (any other's won't fit and can cause fire and electrocution if forced in) Always bring a breaker with you to the store or at least get the name off the box or breaker itself.

  • 3. 

    You have fuses instead of breakers in your house. One is blown. How do you know it's an overload, and not a short circuit?

    • A.

      The fuse is totally melted

    • B.

      The glass on the fuse is broken

    • C.

      The filament is broken inside the fuse

    • D.

      The glass is blackened out.

    Correct Answer
    C. The filament is broken inside the fuse
    Explanation
    An overloaded fuse will show a broken filament. A short circuit will show blackened out glass. An overloaded circuit is too much power on that line/branch. A short circuit is bare wires touching, or wires hooked up wrong.

  • 4. 

    What does each colour represent in 4-conductor electrical wire?

    • A.

      Red=hot, Black=hot, white=neutral, green=ground

    • B.

      Red=neutral, Black=hot, white=ground, green=hot

    • C.

      Red=ground, Black=neutral, White=hot, Green=hot

    • D.

      Red=hot, Black-ground, White=hot, Green=neutral

    Correct Answer
    A. Red=hot, Black=hot, white=neutral, green=ground
    Explanation
    Red and Black are ALWAYS hot. White is neutral. This is the wire that carries the current back to the breaker box or fuse box to complete the circle of current. Green (or bare copper) is always ground. (Remember Red Hot as in the candy. Black Gold as in Oil, Green and Ground both start with G)

  • 5. 

    What do you do if you hang your Christmas lights and you have a female plug at the end by the outlet?

    • A.

      Buy a double male adapter.

    • B.

      Take down the lights and restring them.

    • C.

      Buy a double female adapter.

    • D.

      Buy a male/female adapter.

    • E.

      Run an extention cord from the opposite end.

    Correct Answer(s)
    B. Take down the lights and restring them.
    E. Run an extention cord from the opposite end.
    Explanation
    *Double male adapters do not exist. United Laboratories did approve them many years ago, but they caused too many fires. The reason being, the direction the electricity was flowing was crossing.
    *Double female adapters do not exist for the same reason.
    *A male/female adapter defeats it's purpose, simply becuae a male end plugs into a female end so no adapter is needed to begin with.

  • 6. 

    The circuit breaker in a typical household light circuit is rated for how many amps?

    • A.

       2

    • B.

       20

    • C.

      200

    • D.

      2,000

    • E.

       20,000

    Correct Answer
    B.  20
    Explanation
    The circuit breaker in a typical household light circuit is rated for 20 amps. This means that it can handle a maximum current of 20 amps before tripping and interrupting the flow of electricity. It is important for the circuit breaker to be properly rated in order to protect the circuit and prevent overheating or electrical fires.

    Electric energy is produced by the________of charges.

    • A.

      Cessation

    • B.

      Separation

    • C.

       combination

    • D.

      Amalgamation

    • E.

      Condensation

    Correct Answer
    B. Separation
    Explanation
    Electric energy is produced by the separation of charges. This means that when positive and negative charges are moved apart, they create an electric potential difference, which results in the flow of electric current. This separation of charges can occur through various means, such as rubbing two objects together or through chemical reactions in batteries. Once the charges are separated, they can be harnessed to do work and generate electric energy.

    By design, wires with the highest resistance are built into ...

    • A.

      Clocks

    • B.

       toasters

    • C.

       telephones

    • D.

       stereo speakers

    • E.

      Printed circuit boards

    Correct Answer
    C.  telephones
    Explanation
    Wires with the highest resistance are built into telephones because high resistance helps to reduce the amount of electrical current flowing through the wires. This is important in telephones as it helps to prevent overheating and damage to the components. Additionally, high resistance can also help to reduce noise and interference in the telephone signal, resulting in clearer communication.

    What is it that flows from a battery to a light?

    • A.

      Atoms

    • B.

       photons

    • C.

      Protons

    • D.

      Neutrons

    • E.

      Electrons

    Correct Answer
    E. Electrons
    Explanation
    When a battery is connected to a light, the flow of electric current occurs. Electric current is the movement of electric charge, and in this case, it is the movement of electrons. Electrons are negatively charged particles that flow from the negative terminal of the battery to the positive terminal. As the electrons flow through the circuit, they transfer energy to the light bulb, causing it to emit light. Therefore, the correct answer is electrons.

    The charged regions of clouds that produce lightning are most similar to giant ...

    • A.

      Capacitors

    • B.

      Generators

    • C.

      Transformers

    • D.

      Electromagnets

    • E.

      Incandescent lamps

    Correct Answer
    A. Capacitors
    Explanation
    The charged regions of clouds that produce lightning are most similar to giant capacitors. Capacitors store electrical energy in an electric field between two conductive plates, and in the case of clouds, the charged regions act as the plates. Just like a capacitor, the clouds accumulate and store electrical charge until the potential difference becomes large enough to create a discharge in the form of lightning. This discharge releases the stored electrical energy, similar to how a capacitor discharges when connected to a circuit.
