How much in money is 49 units of electricity compared to 132 units?

Answer 1

The cost of electrical energy is determined by the tariffpresented by your electricity supply company. A tariff is a scale of charges based on the price of one 'unit', or 'kilowatt hour', of energy consumed, and this price varies according to the number of units used. For example, the first x units will be charged at a certain rate; the next y units will be charged at a different rate; and so on. In some countries, the moreenergy you use, the lower the cost per unit becomes, whereas in other countries, the more energy you use, the higher the cost per unit becomes. On top of the cost per unit, most electricity supply companies also include a regular 'standing charge', which covers the cost of rental of the energy meter, meter reading, bill preparation, etc.

So, in order to answer your question, you must obtain a copy of your electricity supply company's tariff, and you will have to work it out for yourself based on that tariff. A straightforward answer is impossible, as tariffs vary from company to company, and from country to country.
