Define kilowatt-hour. How many joules are equal to 1 kilowatt-hour? Switch Flag Bookmark. What does an electric circuit mean? Electric circuit is a continuous and closed path along which an electric current flows.
Define the unit of current. What is meant by saying that the potential difference between two points is 1 V? The potential difference between two points is 1 volt when, one joule of work is done in moving one coulomb of positive charge from one point to the other point.
Name a device that helps to maintain a potential difference across a conductor. Battery is a device that helps to maintain potential difference across a conductor. The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.
The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J ; for example, 1 joule can be written as 1 J. You are here. Kilowatt-hour Value:. Results in Joules:. Do you want to convert joules to kilowatt-hours?
