Given:

The resistance is,

$R=50\text{ ohm}$

The current through the resistor is,

$i=2.0\text{ A}$

To find:

The power dissipated by the resistor

Step-by-step explanation:

The power dissipated by the resistor is,

$\begin{gathered} P=i^2R \\ =(2.0)^2*50 \\ =4.0*50 \\ =200\text{ W} \end{gathered}$

Hence, the power dissipated by the resistor is 200 W.
