In how many hours a 1000 watt AC will consume one unit of electricity?
Correct answer: B. 1 hr
- A. 0.5 hr
- B. 1 hr
- C. 1.5 hr
- D. 2 hr
Explanation
The power of the AC is given as 1000 watts, which is equivalent to 1 kilowatt. One unit of electricity is defined as 1 kilowatt-hour (kWh). Therefore, a 1000 watt device will consume one unit of electricity in one hour. To understand why the other options are incorrect: 0.5 hours would only consume 0.5 units, 1.5 hours would consume 1.5 units, and 2 hours would consume 2 units of electricity. Thus, the correct answer is 1 hour.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
