Question

an electic device rated 1000watt 220 volt is connected t the mains .Calculate

Answer 1

Given that,

power = p = 1000 watt

voltege = v = 220 volt

current = I = ?

P =VI

I= P/V

I= 1000/220

I= 4.54

Answer 2

p=1000 W

V=220 v

Therefore,

p=V*I

=> I=p/V

=1000/220

=100/22

=4.5454...

=4.54
