    A battery of emf 10 V and internal resistance \[3\,\Omega \] is connected to a resistor as shown in the figure.  If the current in the circuit is 0.5 A.  then the resistance of the resistor will be                  [MH CET 2000; Pb. PMT 2000]

    A)         19 W

    B)         17 W

    C)         10 W

    D)         12 W

    Correct Answer: B

    Solution :

                                             \[i=\frac{E}{R+r}\Rightarrow 0.5=\frac{10}{R+3}\]Þ 10 = 0.5R + 1.5 Þ R = 17W.
