Question

What is the current rating of an electric appliance of a 2kW power rating when connected to a $200V$ source?

Answer 1

Power ($P$) = $2kW=2000W$

Voltage for household ($V$) = $200V$

We know that $Power\left(P\right)=V\times I$, where $I$ is the current.

$\therefore 2000=200\times I$

$\Rightarrow I=\frac{2000}{200}=10A$
