Question

If in a office 10 tubes of 40 w, 5 fan of 75W and 2 ac of 1500 w are used for 8 hours a day .calculate the energy comsumed per day in commerical units of energy

Answer 1

Power consumption by10  tube lights in a day=40W x 10X8=3200WH
Power consumption by 5 fans in a day=75Wx5x8=3000WH
Power consumption by 2 a.c in a day=2x1500x8=24000WH
total power consumed by all appliances =3200+3000+24000
=30200WH
=30200WH/1000=30.2KWH
Hence energy consumed per day=30.2KWH
