plss tell me how to solve it..​

Answer 1

Answer:

Energy consumed per day = 375 Wh

Explanation:

Power rating P = 750 W

Time of consumption t = 30 min = 30/60 hr = 0.5 hr

Energy consumed per day E = Pt

                                               = 750 x 0.5    

                                                = 375 Wh
