 A cell, a resistor, a key, and an ammeter are arranged as shown in the circuit diagrams in Figure 12.1. 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 

Answers (1)

Hence, the correct answer is option (d).

Explanation:-
A cell, a resistor, a key, and an ammeter are arranged in series as shown in the circuit diagrams.


The current is given as:

I = V/R


V and R are equal in all three circuits, so the current remains constant.
In series, the order of elements in the circuit does not matter to the amount of current flowing through it.
