One watt is equal to which of these values?

1 joule/hour

1 joule-hour

1 joule/second

1 joule-second

Correct option: 1 joule/second

Explanation:

The Watt is the unit of measure of power of the International System of Units, it is represented by the letter W in uppercase, it owes its name to the Scottish James Watt.

The watt is a unit of power that equals 1 joule per second (1J / s). Or the work of moving a mass of 1 kilogram, a distance of 1 meter in a second of time. Hence the equivalence since force by distance is work and time divided by power. A horsepower equals 775 W. Expressed in units used in electricity, one watt is the electrical power produced by a potential difference of 1 volt and an electric current of 1 ampere (1 voltampere).

1 W = 1 J/s

Watt is the unit of measure for power.

Joule is the unit of measure for the energy and the second is the unit of measure for time.
