Solution

Given:
            V = 220 V
            P = 2.2 kW = 2.2 x 103 w
            t = 3 h

Electrical energy, E = P x t
                               = 2.2 kW x 3 h
                               = 6.6 kWh

Current drawn, I = P/V
                          = `2.2x10^3/220`
                           = 10 A 

  Is there an error in this question or solution?
