Question

a 1500 watt electric geyser is used to everyday for 2 hours calculate the electrical energy​

Answer 1

Explanation:

firstly,

       1500W = 1500/1000KWh

                    =>1.5KWh

       Time taken = 2hrs

       Now power = energy consumed/time taken

       therefore, 1.5 = energy consumed/2hrs

       so, energy consumed = 1.5 * 2              

                                            =>3KWh

        So, the energy consumed = 3KWh
