Question

For a heater rated at 4kw and 220v calculate the current

Answer 1

Explanation: if it is connected to 220 V supply then

P=VI

4000=220*i

i=4000/220=18.18A

Answer 2

Answer:

18.1 ampere.

Explanation:

We know that power equals to v*i.

and kwh is w*1000.

4000=220*I.

I=4000/220.(kwh/volt)

I=18.1 ampere
