If the reading of ammeter A1 in figure is 2.4A, what will the ammeters A2 and A3 read? Neglect the resistances of the ammeters.
1.6A, 4A
Given,
Current through A1 ammeter, i-i1= 2.4A
Formula used:
Depending on the resistance offered by each paths of a circuit, the current split inversely. The voltage across the two branches will be same as they are connected parallel.
Solution:
The current going through Ammeter A3 will split into two. To find the current in two branches, let’s equate the voltage in each branches.
Hence,
By substituting the value of i-i1= 2.4A, we get i1 that goes through ammeter A2 as,
Hence the total current i, passing through A3
Hence the current through A2 and A3 are 1.6A and 4A.
