Define the term 'Watt'.
A Watt is the unit of measure for calculating the power of a circuit or work done per unit time.
A single Watt (W) is equivalent to one joule (J) per second (S), where a Joule is a unit of measurement of the energy.
For example, 1 watt is equivalent to 1 ampere flowing through a circuit with a 1 volt electric potential difference.
1 Watt is equivalent to doing 1 Joule of work per second.
