Work out the current through a television with a power of 0. 8kw if it uses the 230v mains supply. Give your answer to 1 decimal

storchak [24]

The current through the television is 3.5 A.

<h3>Electrical power</h3>

Electrical power P = IV where I = electric current and V = voltage.

Since we require the current through the television with a power of 0.8 kW which uses 230 V mains supply, we make I subject of the formula.

<h3>The current </h3>

So, I = P/V

Given that P = 0.8 kW = 800 W and V = 230 V,

substituting the values of the variables into the equation, we have

I = P/V

I = 800 W/230 V

I = 3.48 A

I ≅ 3.5 A

So, the current through the television is 3.5 A.
