1 watt equals how many joules per second?

Explanation:
Power is the rate at which energy is transferred. The watt is defined as one joule of energy per second. So if energy is transferred at a rate of 1 joule every second, that rate is 1 watt. Therefore 1 watt equals 1 joule per second. The other values correspond to different rates: 0.1 joules per second is 0.1 watt, 2 joules per second is 2 watts, and 10 joules per second is 10 watts.
