Question

A flat-screen television uses 3 amps and has a power rating of 300 watts.

How many volts does it need?
A.303 volts
B.100 volts
C.900 volts
D.297 volts

Answer 1

I think the answer would be B.

Answer 2

Answer : The voltage of flat screen television is 100 V.

Explanation :

It is given that,

Current used by a flat screen television,
`I=3\ A`

Power rating,
`P=300\ W`

We have to find the amount of voltage used by television.

Power of an electrical equipment is given by :

`P=VI`

or

`V=(P)/(I)`

`V=(300\ W)/(3\ A)`

`V=100\ V`

So, the correct option is (B) "100 V"

Hence, this is the required solution.
