      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?

    Answer:

                      Let the experimental set up comprises of three resistors and of three different values such as and which are connected in series. Connect them with a battery of 6 V, an ammeter and plug a key, as shown in figure,   The key K is closed and the ammeter reading is recorded. Now, the position of ammeter is changed to anywhere in between the resistors again, the ammeter reading is recorded each time. It's observed that there was identical reading each time, which shows that same current flows through every part of the circuit containing three resistances in series connected to a battery.
