Energy = Power × Time
= 150 Watt × 20 hous
= 3000 Wh
= 3 kWh
= 3 BOT units
Energy consumed per day is 3 BOT units
Energy consumed in one month (≈ 30 days) = 3 × 30 = 90 BOT units
= 150 Watt × 20 hous
= 3000 Wh
= 3 kWh
= 3 BOT units
Energy consumed per day is 3 BOT units
Energy consumed in one month (≈ 30 days) = 3 × 30 = 90 BOT units

20 hrs in 1 day
therefore in 30 days it is used for 20*30 =600hrs. we know energy consumed =vIt i.e
P(in KWh)t(in hrs)
=150/1000 KWh*20 hrs =3 KWh i.e 3 BOT unit
