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?

Explanation

The experimental set up comprises three resistors `R_(1),R_(2),andR_(3)` of three different values such as `1Omega,2Omegaand3Omega` which are connected in series. Connected them with a battery of 6 V, an ammeter and plug key, as shown in figure.

The key K is closed, and the ammeter reading is recorded. Now, the position of ammeter is changes to anywhere in between the resistors and the ammeter reading is recorded each time. It.s observed that there was identical reading each time, which shows that some current flows through every part of the circuit containing three resistances in series connected to a battery.
