A cell, a resistor, a key, and ammeter are arranged as shown in the circuit diagrams of Figure. The current recorded in the ammeter will be:
(a) maximum in (i).
(b) maximum in (ii).
(c) maximum in (iii).
(d) the same in all the cases.
In circuits where components are connected in series , the amount of current flowing through the circuit is not affected by the order in which components are connected.
Therefore, In all the 3 given circuits, the current recorded in the ammeter will be the same .
So, the correct answer is (d).
