Calculate the electricity units for a month of 31 days, if the following devices are used as specified :
(a) 3 bulbs of 40 W for 6 hours.
(b) 4 tube lights of 50 W for 8 hours
Answers
Answer:
(a) electricity consume = power * time
= (3*40) * 6 watt-hour
= 720 watt- hour
= 720/1000 kilowatt hour
=0.72 kilowatt hour or BOT unit
Electricity units for 31days= 0.72 * 31 BOT unit
= 22.32 BOT unit
(b) electricity consume =power*time
= (4*50)*8
= 1600watt hour
= 1600/1000 kilowatt hour
= 1.6 kilowatt hour or BOT unit
Electricity units for 31days= 1.6*31BOT unit
= 49.6 BOT unit
