Which of the following is not one of the seven base SI units?

Explanation:
The watt is a derived unit of measurement in the International System of Units (SI) that expresses power, which is the rate at which energy is used or produced. It is defined as one joule per second and is not one of the seven base SI units. The base SI units include the meter (for length), second (for time), and kilogram (for mass), among others. The meter measures distance, the second measures time, and the kilogram measures mass, all fundamental quantities on which other units, like the watt, are built. Understanding the distinction between base and derived units is crucial as it forms the foundation for various scientific calculations and measurements in electrical science and other fields.
