Question

Work out the current through a television with a power of 0.8 kW if it uses the 230 V mains supply. Give your answer to 1 decimal place.

Answer 1

Answer:

the current is 3.5 A

Explanation:

The computation of the current is shown below:

As we know that

Current [A] = Electrical power [W] ÷ Potential difference [V]

Now convert KW TO W = × 1000

So, the current is

= 800W ÷ 230V

= 3.5 A

Hence, the current is 3.5 A
