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

  • question_answer
    Heat produced in a wire of resistance R due to current flowing at constant potential difference is proportional to [MP PET 1993]

    A)            \[\frac{1}{{{R}^{2}}}\]      

    B)            \[\frac{1}{R}\]

    C)            R

    D)            \[{{R}^{2}}\]

    Correct Answer: B

    Solution :

               At constant p.d., heat produced \[=\frac{{{V}^{2}}}{R}\,i.e.\,H\propto \frac{1}{R}\]
