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

  • question_answer Two resistors having equal resistances are joined in series and a current is passed through the combination. Neglect any variation in resistance as the temperature changes. In a given time interval                                 [MP PMT 1999]

    A)            Equal amounts of thermal energy must be produced in the resistors

    B)            Unequal amounts of thermal energy may be produced

    C)            The temperature must rise equally in the resistors

    D)            The temperature must rise unequally in the resistors

    Correct Answer: A

    Solution :

                       \[P={{i}^{2}}R\]            (i and R are same)            So P will be same for given resistors.
