Question

A color-TV set has a power rating of 320 W.How much current does this set draw from a potential difference of 110V?​

Answer 1

Explanation:

Favorite Answer

current, or amperage, is wattage/voltage

320/120= 2.667 amps

Answer 2

Given,

The power rating of the color-T.V set = 320 W

To Find,

The amount of current that the T.V can draw from a potential difference of 110 V.

Solution,

The formula for calculating the power of an object is

Power = V*I

where V denotes the potential difference and I denotes the current drawn.

In this case,

Power = 320 watts

Potential difference = 110 V

So,

320 = 110*I

I = 320/110

I = 2.9 ampere

Hence, the current drawn by the T.V set is 2.9 amperes.
