The current through the television is 3.5 A.
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.
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.
