# How will you infer with the help of an experiment that the same current flows through every part of the circuit containing three resistances in series connected to a battery?

(a) Steps-

1. Connect an ammeter between  and  and note down the current.

2. Repeat the same by connecting it between , and then  and

3. You will find that all the notings are same. hence, same current flows throughout a circuit with service connection.

(b)

(i) The two  restores are in parallel the resultant resistance will be

The circuit could be drawn as

Let's assume current i is flowing in the circuit

(ii) The current in both ammetur  and  will be same because they are connected in series

Hence difference between reading will be zero.
