JEE Main & Advanced Physics Current Electricity, Charging & Discharging Of Capacitors / वर्तमान बिजली, चार्ज और कैपेसिटर का निर Question Bank Thermo Electricity

  • question_answer
    The temperature at which thermal electric power of a thermo couple becomes zero is called      [MP PMT 2001]

    A)            Inversion temperature    

    B)            Neutral temperature

    C)            Junction temperature      

    D)            Null temperature

    Correct Answer: B

    Solution :

               Thermo-electric power \[P=\frac{dE}{d\theta };\] at tn, E ® maximum. So P ® zero.
