You will need
- receipt of payment for the supply of electricity;
- -the current meter readings ("end index");
- counter value at the time of payment of electricity last month ("initial index");
- -the size of the tariff on your electricity bill this month.
Locate the meter, which is not always in the open, and sometimes placed in a special vandal-proof Cabinet or box. If the door of the Cabinet is transparent, then open it and it is enough to see the dial of the counter and to rewrite all the numbers, not forgetting to separate the last one from the rest of the numbers with a comma. This number is the final figure, which will need to enter the receipt of payment supply your home with electricity.
Take the receipt for payment and find it in column "initial level," "ending index" and "flow". The final figure you found out, removing the current counts from the counter - enter its value in the appropriate box, rounding to the nearest integer (the first five numbers before the comma). Then complete the column "initial index" is the counter reading, which was recorded at the time of previous payment a month ago, it should be listed in the same receipt.
Subtract the final figure from the start, thereby obtaining the number consumed per month kilowatt, and enter the value in the column "flow". Now you know the tariff for your electricity bill this month - the rate is specified in the payment receipt. Multiply the flow rate (the amount of consumed kilowatt) rate (price per kilowatt) and get the amount in a given month you have to pay for electricity or for "light", as they say in the nation.
Be careful opening the door, vandal-resistant Cabinet that is placed in the counter, and closer to the device next to it might be the fuse box is under high voltage!
