Question

An electric kettle rated at 220 V, 2.2 kW, works for 3 hours. Find the energy consumed and the current drawn.

Answer 1

Answer:

I = 10 A   & 6.6 KWh

ExplIanation:

    P = V I                    

    I = P / V                

   R = (220)²/ 4000

    I =  2200 / 220      

    I = 10 A            

energy consumed in KWh = watt × time in hours /1000

energy consumed in KWh = 2200×3/1000

                                            =  6.6 KWh

Answer 2

Answer:

Current = 10 A

Energy = 6.6 KWh
