Question

Electric energy in kilowatt-hours (kWh) is equal to:

विकल्प

• $$\frac{\text{Power (in W)} \times 1000}{\text{time (in h)}}$$

• $$\frac{\text{Power (in W)} \times \text{time (in h)}}{100}$$

• $$\frac{\text{Power (in W)} \times \text{time (in h)}}{1000}$$

• $$\frac{\text{Power (in W)} \times \text{time (in h)}}{1000,000}$$

Answer 1

$$\frac{\text{Power (in W)} \times \text{time (in h)}}{1000}$$

Explanation:

Convert power from watts to kilowatts by dividing by 1000. Then multiply by time in hours to get energy in kWh. The other options use the wrong operation or conversion factor.
