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

Expert Answer:

Initial current depends on the initial drift of electrons (which varies according to the arrangement in each case). However, the current gets stable almost instantly and all the three ammeters show the same reading.
