Hello everyone.
00:01
We have a question in which we have given that in a house we have different different appliances.
00:08
So in the house we have three bulbs.
00:12
So we have three bulbs having a power of 100 watt each and which are lighting for the five hour daily.
00:21
So these three bulbs is having a power which is equals to 100 watt.
00:29
And the basically the time, basically the daily time, for which they are lighten.
00:37
So daily time, we have also given that.
00:40
So daily time which is given that five hours per day, five hours per day.
00:48
Similarly, we have two fans in the house and these fans are having a power of 50 watt each and they are working for 10 hours daily.
01:06
So daily time, we can again say that the daily working time is equals to 10 hours per day.
01:19
And we have also one heater, one electric heater in the house.
01:26
And this electric heater is having a, this is having a energy of one kilowatt hour.
01:33
So we can say that it is having a energy consumption.
01:41
Energy consumption by this heater is equals to 1 kilowatt hour and it is working for so we can say that the working hour so this is working for half day half an hour so half an hour we can say that half hour daily so this is the given data in the question and what we need to find we need to find the total energy consume so we need to to find the total energy consumed in 31 days.
02:31
So let's see how can we do this question.
02:34
So first of all, we need to find the energy consumption for each day.
02:38
So therefore, first of all, we will find for the bulbs.
02:44
So first of all, for the bulbs, but we can say that the energy consumed will be equal to that is eb, which is equal to number of the bulbs.
03:03
Of bulbs multiplied by power of each bulb multiplied by time for which they are working.
03:10
So therefore what we can say, electric energy consume, which is bulk total number of bulb which we have given three, multiplied by power is given that hundred, multiplied by time which they are working for five hours.
03:24
So it is coming out to be, so power of bulb, that means the energy consumed is coming out to be 1 .5 kilowatt hour...
