A 50 ohm resistor in a circuit has a current flowing through it of 2.0 A. What isthe power dissipated by the resistor? (Use P-OVI - R=V)OA. 25 WOB. 100 WC. 200 WOD. 50 W

Answer :

Given:

The resistance is,

[tex]R=50\text{ ohm}[/tex]

The current through the resistor is,

[tex]i=2.0\text{ A}[/tex]

To find:

The power dissipated by the resistor

Explanation:

The power dissipated by the resistor is,

[tex]\begin{gathered} P=i^2R \\ =(2.0)^2\times50 \\ =4.0\times50 \\ =200\text{ W} \end{gathered}[/tex]

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