Answer 2

If A1 reads 0.50 A, then the A2, A3, A4 and A5 will read 0.25 A each.

Explanation:

At present, it is to be noted that A1 is divided equally. A3 and A2 can be found to have same current, which is 0.25 A. And, A5 and A4 are also found to have same current, which equals 0.25 A because same resistance can be found in both lamps.  

In the question, it is given that both the lamps are similar, so we can find equal resistance.  

• 0.5 A current is read by the ammeter A1. So, now the current will now get equally distributed as resistance in two branches.
• So, the ammeters A4 and A2 will have 0.25 A each. It can be seen that A5 and A3 are connected with A4 and A2 in series. So, these will also reach 0.25 A each.
