    In an electric heater 4 amp current passes for 1 minute at potential difference of 250 volt, the power of heater and energy consumed will be respectively :

    A)  1 kvs 60 kj                          

    B)  0.5 kw, 30 kj

    C)  10 kw, 600 kj                    

    D)  none of these

    Correct Answer: A

    Solution :

    Here: V = 250 volt, i = 4 amp, t = 1 minute = 60 sec The power is given by \[-6\times {{10}^{6}}C,\] \[2.4\times {{10}^{-3}}\] watt \[2.4\times {{10}^{-9}}N\]                            The energy consumed is E =power \[1.5\times {{10}^{-3}}N\] time \[1.5\times {{10}^{-3}}N\]
