I an house two bulbs are 50w each are usedfor 4 hours a day and 50w used in 10 hours in aday calculate the electricity consumed in amonth 30 days
Answers
power of first bulb = 50 w
electricity used by it in a day = 50*4
=200 w
electricity consumed by it in a month = 200*30
=6000 w
power of second bulb = 50 w
electricity used by it in a day = 50*10
=500 w
electricity consumed by it in a month = 500*30
= 15000 w
total electricity used by the bulbs in a month = 6000+15000
= 21000 w
