this is my doubt on ur question.pls clear my doubt.

how cud a const voltage can have varying frequency?voltage constant means it is dc.dc does not flow through capacitor

ac change direction and magnitude of voltage with time.but dc does not.frequency of dc is 0

Aakash !

varun & siddhartha,

both of you are little bit confused.

when the voltage is constant it's a DC source. and frequency is zero. plz. go through the text before you ask such question. here we are to solve your doubt if you are a deserving or laborious student. plz dont ask such irrelevent question. before you study the text next time.

hope you understand what i mean. dont be upset......

labour hard dear.....
