Answer:
<em>An object is said to be rated </em><em>1 Watt </em><em>when it performs a work worth </em><em>1 Joule </em><em>in </em><em>1 second.</em>
Explanation:
<em>We know that power is rate of doing work or Work done in a given period of time.</em>
<em>Power is simply given by the formula:</em>
