Question

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 1

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.
