Two parallel resistors with resistance values in the ratio 9:1 are connected. Calculate the power dissipation ratio.

 We can take into account the relationship between power and resistance.,

 i.e. $\text{ Power }=\frac{{\text{ voltage }}^2}{\text{ resistance }}$. 

The voltage across the resistors will be the same because they are linked in parallel. As a result of this relationship, power and resistance are inversely related.

Thus, $\frac{P_1}{P_2}=\frac{R_2}{R_1}=\frac{1}{9}$

As a result, the power dissipated is in the ratio is 1:9.
