Question

A flat screen TV uses 120 Watts. How much energy is used up if it is left on for 15 minutes? Question 25 options: 4 J 15 J 0.67 J 108,000 J

Answer 1

Option d (108,000 J) is the correct answer.

Step-by-step explanation:

The given values are:

Power,

P = 120 Watts

Time,

t = 15 min.

i.e.,

= 900 sec

As we know,

⇒
`P=(W)/(t)`

So,

⇒
`W=P* t`

On substituting the given values, we get

⇒
`=120* 900`

⇒
`=108,000 \ J`
