Questions and Answers
  • 1. 

    True or False, Auto ranging multimeters can switch between the value ranges automatically?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Auto ranging multimeters are designed to automatically switch between different value ranges based on the input being measured. This feature eliminates the need for manual range selection, making it easier for the user to obtain accurate readings. With auto ranging, the multimeter detects the magnitude of the input signal and adjusts the range accordingly, ensuring that the measurement is within the optimal range for accuracy. Therefore, the statement "Auto ranging multimeters can switch between the value ranges automatically" is true.

    AC voltage is power that is supplied by?

    • A.

      Solar Energy

    • B.

      Standard House Power

    • C.

      Geothermal Energy

    • D.

      Battery Power

    Correct Answer
    B. Standard House Power
    Explanation
    Standard House Power refers to the electrical power that is supplied by the utility company to residential houses. It is the most common and widely used source of AC voltage for powering household appliances and devices. This power is generated in power plants using various sources such as fossil fuels, nuclear energy, or renewable sources like hydroelectric power. It is then transmitted through power lines to homes, where it is distributed and used for various electrical needs.

    True or False, While testing voltage, the mulitmeter is connected to the tested component in a parallel connection?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When testing voltage, the multimeter is connected in parallel to the component being tested. This means that the multimeter is connected across the component, with the positive lead connected to the positive terminal and the negative lead connected to the negative terminal. This allows the multimeter to measure the voltage across the component without affecting the circuit or altering the voltage being measured.

    A resistance reading is considered a __________________ reading.

    • A.

      Capacitance

    • B.

      Voltage

    • C.

      Ohms

    • D.

      Micro Fared

    Correct Answer
    C. Ohms
    Explanation
    A resistance reading is considered an "Ohms" reading because resistance is measured in ohms. Ohms is the unit of measurement for electrical resistance, which is the opposition to the flow of electric current in a circuit. Therefore, when measuring resistance, the reading is expressed in ohms.

    True or False, To perform a resistance test you must connect to the component in series?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    To perform a resistance test, you do not need to connect to the component in series. Resistance can be measured by connecting the test leads of the multimeter to both ends of the component, regardless of whether it is connected in series or parallel. Therefore, the statement "To perform a resistance test you must connect to the component in series" is false.

  • 6. 

    Continuity testing is simular to what other type of testing?

    • A.

      Voltage

    • B.

      Current

    • C.

      Micro Fared

    • D.

      Resistance

    • E.

      All of the above

    Correct Answer
    D. Resistance
    Explanation
    Continuity testing is similar to resistance testing because both involve checking the flow of electrical current through a circuit. In continuity testing, a circuit is tested to determine if there is a complete path for the current to flow, indicating that there is no break or interruption in the circuit. Similarly, resistance testing is done to measure the resistance of a component or circuit, which indicates how much it opposes the flow of current. Therefore, the correct answer is resistance.

    True of False, When testing current you must disconnect power to receive a proper reading?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    When testing current, it is not necessary to disconnect power to receive a proper reading. Current can be measured using a current measuring device, such as an ammeter, which is designed to measure current without the need to disconnect power. This allows for safe and accurate measurements to be taken without interrupting the flow of current in the circuit.

    What are the 2 styles of multimeters? _____________ & ______________

    • A.

      Analog

    • B.

      LCD

    • C.

      Digital

    • D.

      AC Delco

    • E.

      None of the above

    Correct Answer(s)
    A. Analog
    C. Digital
    Explanation
    Analog and digital are the two styles of multimeters. Analog multimeters use a needle or a pointer to indicate the measurement on a scale, while digital multimeters display the measurement as a numeric value on an LCD screen.

    True or False, No damage or injury can occur when misusing a multimeter? 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given answer is False. This means that the statement "No damage or injury can occur when misusing a multimeter" is incorrect. Misusing a multimeter can indeed lead to damage or injury. Multimeters are electrical testing devices that can measure voltage, current, and resistance. If they are not used properly, such as using the wrong settings or not following safety precautions, they can cause electric shocks, short circuits, or damage to the device being tested. Therefore, it is important to use multimeters correctly and be aware of the potential risks involved.

    A multimeter has virtually NO _____________ between the leads. This make for a more accurate reading.

    • A.

      Voltage

    • B.

      Current

    • C.

      LCD

    • D.

      Resistance

    • E.

      None of the above

    Correct Answer
    D. Resistance
    Explanation
    A multimeter has virtually no resistance between the leads. This means that when measuring voltage, current, or resistance, the multimeter will not introduce any additional resistance that could affect the accuracy of the reading. By having minimal resistance, the multimeter can provide a more accurate measurement of the electrical quantities being tested.
