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

  • question_answer Two resistors of \[6\,\Omega \] and \[9\Omega \] are connected in series to a 120 volt source. The power consumed by the \[6\,\Omega \] resistor is     [SCRA 1994]

    A)            384 W                                      

    B)            576 W

    C)            1500 W                                   

    D)            1200 W

    Correct Answer: A

    Solution :

                       Current through the combination \[i=\frac{120}{(6+9)}=8\,A\]                    So, power consumed by 6 W resistance            \[P={{(8)}^{2}}\times 6=384\,\,W\]
