Question

1 kW power is equal to _______. (kW stands for kilowatt.)

A.

1 J/S

B.

1000 J/s

C.

​10 J/s

D.

100  J/s

Correct option is B

The correct answer is: (B) 1000 J/s

Explanation:
1 kilowatt (kW) is a unit of power, and it is equal to 1000 joules per second (J/s). Power is the rate at which energy is used or produced, and the watt (W) is the SI unit of power, where 1 watt equals 1 joule per second (J/s). Therefore:

1 kW=1000 W=1000 J/se1 \, \text{kW} = 1000 \, \text{W} = 1000 \, \text{J/s}e

This means 1 kilowatt of power is equivalent to 1000 joules of energy used or produced per second.

Information Booster:

  • Power is measured in watts (W), where 1 watt is the rate of energy transfer of 1 joule per second (1 J/s).

  • A kilowatt (kW) is a more commonly used unit for larger power quantities, such as in electrical systems.

  • The relationship between watts and joules is fundamental in understanding energy consumption and electrical power.
