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? 

Answers (1)

Join three resistors of different values in series. Connect them with a battery, an ammeter and a plug key, as shown in Figure. Let us assume that the resistors have values 1\Omega, 2\Omega, 3\Omega etc., and a battery of 6 V is used.

Plug the key. Note the ammeter reading. Change the position of ammeter to anywhere in between the resistors. Note the ammeter reading each time.

We can notice that where ever we connect the ammeter, the current is always the same.
