An electric kettle connected to the 230V mains supply draws a current of 10A. Calculate: a) the power of the kettle b) the energy transferred in 1 minute

Answer:

Given in the question,

V = 230V

I = 10amp

a) We know that,

P = VI

Substituting the values of V & I, we get

P = 2300 watt = 2300 J/s

b) Also, energy consumed in one minute = PT

= 138000 J
