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.

Question

Philoid · Accepted Answer

(a) Here, V = 230V, I = 10amp

We know that, P = VI

P = 230X10

P = 2300watt = 2300 J/s

(b) The energy transferred in 1 minute. = P x t = 2300 J/s x 60s = 138000 J
