Transducers must operate under ___________(a) zero electromagnetic fie

1.	Transducers must operate under ___________(a) zero electromagnetic field(b) constant electromagnetic fields(c) varying electromagnetic fields(d) infinite electromagnetic fieldThis question was addressed to me by my school principal while I was bunking the class.The origin of the question is Transducer Selection Factors topic in chapter Transducers of Electrical Measurements
Answer» The correct OPTION is (c) varying electromagnetic FIELDS Explanation: A transducer should operate under strong electromagnetic fields. Generally transducers with a low value of OUTPUT impedance, high value of output voltage and shorter CABLE LENGTH are not susceptible to such interference.
