Ab correct hai ☺
hope helps u
250 watts multiplied with 5 hours daily multiplied with 30 days monthly equals 37500 Watt hours. Divided by a 1000 to get the KWh equals 37.5 KWh.
Four 6 watt lightbulbs equals 24 watts because 4x6=24
So 24 watts multiplied with 4.5 hours daily multiplied with 30 days monthly equals 3240 watt hours . Divided by a 1000 to get the KWh equals 3.24 KWh.
So 37.5 KWh plus 3.24 KWh equals 40.74 KWh a month if the month has 30 days.
40.74 KWh multiplied by the price of 1 KWh will give you the monthly price you pay for using that high energy consuming lightbulb.
I'm not spending that much for powering the whole apartment not yet a for a single bulb. .you must be a dentist or a brain surgeon.
still try this
250*5 watts *28 days= 35 units in Feb month
and 4.5 WATS * 6*28= .756 unit
