Question

The cost of electricity for domestic use is Rs.2.30 per unit. This unit is:
A. 1 Ampere
B. 1 Volt
C. 1 Joule
D. 1 Kilo-Watt-hour

Answer 1

Hint: Electricity pricing changes depending to the mode of supply i.e. single phase, three phase, domestic, commercial, industrial; small, medium or large scale industry. Taking domestic single phase supply for ex, it has four parameters i.e. fixed charge as per attached load & meter charge and variable rent as per actual consumption & electricity cycle duty, which is about 4.5 to 5% of the variable rent.

Complete step by step solution:
Electricity pricing is done based upon the energy consumed. Now energy has various units such as joules, and Kilo-watt- hour. By the way in India, the price of Electricity per unit is variable for different states. The electricity price for domestic consumers is less and for commercial pricing is slightly high. For large scale industries, medium or Small industry, the electricity pricings are variable. The govt of the state provides subsidy on electricity charges for household and industrial connection accordingly.
In India as well as all over the world, the pricing is done on the basis of Kilo-watt-hour of energy units consumed.

Therefore, the current option is (D).

Note: Electricity bill (also referred to as electricity charges or the cost of electricity) can vary country by country or by local places within a nation. Electricity costs are dependent upon many parameters, such as the cost of power generation, Authority taxation or subsidies, locality weather change, transmission and distribution structure, and multi-tier industry rules. The cost or tariffs can also vary depending on the user’s-base, typically by household, commercial, and factory setups.
