An electric kettle connected to the 230 V mains supply draws a current of 10 A. Calculate :

(a) the power of the kettle.

(b) the energy transferred in 1 minute.

Open in App

Solution

Here,

V = 230 volt

I = 10 Ampere

We have

P = V×I

= 230×10 = 2300 W

Now we have the electric kettle transferring 2300 Joule of energy per second.

Energy transferred in 1 min = 2300×60 J

=138000 J
