As such, it is essential that students, especially those continuing higher education, should be able to read and understand academic articles comfortably, and to be able to use Passive / Active Voice to write understandable reports and theses. <> If you want to highlight whether the action was done and not the person who did the action in a sentence, or if you don’t want to send directly to the person, you need to use Passive Voice. In other words the passive transducers derive the power required for transduction from an auxiliary source. An example of a non-electrical conversion, in which a physical element is converted into another physical element, is a simple mercury-filled thermometer. Therefore, tenses also have "active forms" and "passive forms." Active and passive transducers.
