The main part of payment for utilities is the share of power consumption. And each owner does not want to overpay for excess watts. For this reason at many sensitive issue is calculation of optimum quantity of the necessary electric power. It will help to save.
It is required to you
- - calculator;
- - notebook;
- - handle (pencil).
Instruction
1. Make the list of all electric devices which are at you in the apartment. Opposite to everyone write approximate operating time in day. On any household appliances, on the back panel, or in their passports the exact electricity consumption is described. It also should be written down.
2. Count quantity of the bulbs located at you in the apartment. Write down them separately on power. For example, 3 bulbs on 100 W, 2 on 60 W, etc. There is such stereotype that bulbs give the main load of the power supply network. But it absolutely not so. The washing machine for one working hours consumes energy of twenty five hundred watt lamps.
3. Check the list. In it all electric devices which are at you in the apartment have to be written down. Opposite to everyone there has to be time (hours) of work in day (day) and the number of the consumed watts.
4. Increase all kilowatts for hours. The digit which will turn out as a result indicates electric power expense in day. It is necessary to remember that it is only rated digit. Power consumption should be counted proceeding from specific circumstances. For example, if you have small child, then the washing machine works time in 3-4 more, than usually, so it is necessary to adjust digit only when all specific circumstances are considered.
5. Now calculate the power of all lighting equipment. You summarize all capacities of bulbs, for example, 2х100+3х60+1х40, etc. As a result you receive the number of watts which consume all lighting equipment. Increase the turned-out sum for hours/day and you receive the number of the watts consumed by lighting equipment in day. Now to the turned-out result add electric devices. After everything is summarized, increase the received number of kW by 31 and receive monthly expense of the electric power.
