    The resistors whose ratio is 1 : 2, are connected in parallel, the ratio of power dissipated is:

    A)  1 : 2                      

    B)         1 : 4  

    C)  4 : 1                      

    D)         2 : 1

    Correct Answer: D

    Solution :

    Power\[p=\frac{{{V}^{2}}}{R}\] \[\therefore \]  \[p\propto \frac{1}{R}\] \[\therefore \]  \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{R}_{2}}}{{{R}_{2}}}=\frac{2}{1}\]                  \[{{P}_{1}}:{{P}_{2}}=2:1\]
