Dear yashpalguglani@yahoo.co.in

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

We have not understood the query that you have posted. Kindly provide the diagram. Also, kindly mention the position of the key as if the key is connected with the cell, then no current can be recorded by the ammeter.

Regards

Topperlearning Team.
