If the lamps are both the same in the figure given above and if A1 reads 0.50A, what do A2, A3, A4 and A5 read?

Answer:
It is given that the two lamps are identical. So, they will have equal resistance.
 
The ammeter A1 reads 0.5 A current. This current will now get distributed equally in the two branches as resistances are equal.
Hence, the ammeters A2 and A4 will read 0.25 A each. Now, A3 and A5 are connected in series with A2 and A4, so they will also read 0.25 A.
