Question

A Tv has a power rating of 500W.if the current passing through the TV is 25A, what is the potential difference across the TVA.0.05VB.20VC.12,500VD.12.5kV

Answer 1

B. 20V

Step-by-step explanation

The power rating is given by,

`P=V\cdot I`

In this problem, we know that:

• P = 500 W

,

• I = 25 A

And we have to find V. Solving the equation above for V,

`V=(P)/(I)=(500W)/(25A)=20V`

Hence, the potential difference across the TV is 20V.
