Let us consider that a family’s annual electricity consumption is 11,000 kW-h. Assuming the energy expenditures of the family totaled 1,500 per year, calculate the unit price of energy (in $/kWh, with at least 4 significant figures) charged by the utility company.

Respuesta :

Answer:

0.1364 $/kWh

Explanation:

Annual expenditure of the family on electricity = $1500

Total energy consumed during the year = 11000 kWh

Kilowatt hour is the unit of energy which is given by the product of the energy in kW and the number of hours that energy has been used.

Unit price of energy = Annual expenditure / Total energy consumed during the year

[tex]\text{Unit price of energy}=\frac{1500}{11000}=0.1364\ \$/kWh[/tex]

∴ Unit price of energy is 0.1364 $/kWh
