JEE Main & Advanced Physics Current Electricity, Charging & Discharging Of Capacitors Question Bank Heating Effect of Current

  • question_answer Which of the following statement is false

    A)            Heat produced in a conductor is proportional to its resistance

    B)            Heat produced in a conductor is proportional to the square of the current

    C)            Heat produced in a conductor is proportional to charge

    D)            Heat produced in a conductor is proportional to the time for which current is passed

    Correct Answer: C

    Solution :

               \[H={{i}^{2}}Rt\] and \[i=\frac{q}{t}\]. Hence \[H=\frac{{{q}^{2}}R}{t};\,\,\,\therefore \,\,H\propto \,{{q}^{2}}\]
