[amp_mcq option1=”Smaller” option2=”Larger” option3=”Same” option4=”Unpredictable” correct=”option1″]
The correct answer is A. Smaller.
Air cored transducers are smaller than iron cored transducers because they do not have a ferromagnetic core. The ferromagnetic core in an iron cored transducer provides a path for the magnetic field to flow, which makes the transducer larger. The air core in an air cored transducer does not provide a path for the magnetic field to flow, which makes the transducer smaller.
Air cored transducers are typically used in applications where size is a concern, such as in medical imaging and industrial applications. Iron cored transducers are typically used in applications where power is a concern, such as in power generation and motor control applications.
Here is a brief explanation of each option:
- Option A: Smaller. Air cored transducers are smaller than iron cored transducers because they do not have a ferromagnetic core. The ferromagnetic core in an iron cored transducer provides a path for the magnetic field to flow, which makes the transducer larger. The air core in an air cored transducer does not provide a path for the magnetic field to flow, which makes the transducer smaller.
- Option B: Larger. This option is incorrect because air cored transducers are smaller than iron cored transducers.
- Option C: Same. This option is incorrect because air cored transducers are smaller than iron cored transducers.
- Option D: Unpredictable. This option is incorrect because the size of air cored transducers is predictable.
