Understanding Kilovolt-Ampere-Hour (kWh) - A Unit of Energy Measurement

Kilovolt-ampere-hour (kWh) is a unit of energy, which is the product of voltage, current, and time. It is often used to express the amount of electricity consumed by a device or system over a certain period of time.

In more detail, 1 kWh is equal to:

* 1000 watts (W) of power consumed for 1 hour (h)
* 1000 watts x 3600 seconds (s) = 3,600,000 joules (J) of energy

So, if a device consumes 1 kWh of electricity, it has actually consumed 3,600,000 joules of energy. This unit is commonly used in the context of billing for electricity consumption, as well as in the design and specification of electrical systems.
