provide to the transformer?

Answer:

1800W

Explanation:

A TV requires a potential difference of 11.5V and a current of 10A. It uses a transformer to produce the correct potential difference from the mains supply. If the mains supply is 230V, what current does it provide to the transformer? The required electrical power output of a step-up transformer is 1800W.
