The electricity in a house is measured in ______________

Watts
Kilowatt-hours
Amperes
Ohms

The correct answer is: Kilowatt-hours

The measurement of electricity in a house is expressed in kilowatt-hours, representing the total amount of electrical energy consumed over time. This unit helps quantify electrical consumption in a way that relates directly to billing and energy usage monitoring. When you look at your utility bill, the total electricity used is often shown in kilowatt-hours, indicating how many kilowatts of power have been used over the span of an hour. Understanding the other concepts aids in grasping electrical measurements more comprehensively. Watts, for instance, measure instantaneous power and are often used to describe the power of devices, while amperes (or amps) measure the flow of electric current. Ohms quantify electrical resistance. Each of these terms plays a role in understanding the principles of electrical systems but serves different purposes in describing electricity.
