Question

Calculate the electrical energy consumed by 1200w toaster in 30minutes

Answer 1

hloo frnd and your answer is as follows...

-Electrical energy E=Pxt

Here P=1200W=1200/1000=1.2kW

t=30min=30/60=0.5hours

Now E=1.2x0.5=0.6kWh


hope it helps u...☺☺

Answer 2

(i) P = 1200 W  t =30 min = 0.5 h 

Electrical energy (E)=P x t

= 1200 x 0.5  

= 600W/h = 0.6 kWh.

(ii) Energy consumed is 30 days

 = 0.6 x 30 = 18 kWh 

hope it helps u!!
