Question

State whether the following statement is True or False.

kWh is used to express electric energy.

Answer 1

This statement is true.

Explanation:

• The kilowatt-hour (kWh) is the commercial unit of electrical energy, and electricity bills are expressed in kWh (units).
• 1 kWh is the energy consumed when a power of 1000 W is used for 1 hour, i.e., 1 kWh = 1000 W × 3600 s = 3.6 × 10⁶ J.
• kWh expresses energy and not power; electric power is expressed in watts.
