Question

An electrical kettle with a power rating of 1.5 kw is connected across a 230v supply,calculate the current drawn from the supply

Answer 1

1000w=1kw

1500w and 230v

now we should find out current

                -------------

           P=VI

   1500=230 I

   I= 1500/230

therefore current is 150/23

Answer 2

Given Power rating of the electric kettle P = 1.5 kW =1500 W

Potential difference supplied V = 230 V

Now we know

Power (P) = Current (I) × Potential difference (V)

I = (P/V) = 1500/230

I = 6.5 Amp
