[amp_mcq option1=”kilo watt hour” option2=”per household” option3=”voltage” option4=”None of these” correct=”option1″]
The correct answer is A. kilo watt hour.
A kilowatt hour (kWh) is a unit of energy equal to one kilowatt of power expended for one hour. It is a common unit of measurement for electricity consumption.
The other options are incorrect because:
- B. per household is not a unit of energy.
- C. voltage is a measure of electrical potential difference. It is not a measure of energy.
- D. None of these is the correct answer.
I hope this helps! Let me know if you have any other questions.
