Join three resistors of different values in series. Connect them with a battery, an ammeter and a plug key, as shown in Fig. 12.6.
You may use the resistors of values like 1 Ω, 2 Ω, 3 Ω etc., and a battery of 6 V for performing this Activity.
Plug the key. Note the ammeter reading.
Change the position of ammeter to anywhere in between the resistors. Note the ammeter reading each time.
Do you find any change in the value of current through the ammeter?
✅ Answer: The value of the current in the ammeter is the same. i.e., in a series combination of resistors, the current is the same in every part of the circuit or the same current through each resistor.
