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

Question

If the lamps are both the same in the figure given below and if A 1 reads 0.50 A, what do A 2 , A 3 , A 4 and A 5 read?

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.
