an active transformation performs the action on rows. that is why it reduces or increases the no of incoming rows. u cannot by pass the rows through an active transformation.
passive transformations perform the action on columns so doesnot effect the no.of rows passing through it Source: CoolInterview.com

In simple ETL (Extraction, Transformation, & Loading), If source is extracted, goes into transformation, and loads onto the target with no change in row count, that is considered Passive transformation. If the final row count is more or less than the amount coming from source, that is considered Active.

Passive = N number of rows
Active = <>N number of rows Source: CoolInterview.com
