Network Elements and the Concept of Circuit

  1. In figure shown A1, A2, A3 are ideal ammeters. If A1 and A3 read 5 A and 13 A respectively reading of A2 will be—


    1. 8 A
    2. 12 A
    3. 18 A
    4. Indeterminate unless the actual values of R, C and W are specified
Correct Option: B

As we know that ammeter will read the rms value of the current applying the law of vector addition.

A2 3 = A2 1 + A2 2
or A2 2 = A2 3 + A2 1 = (13)2 – (5)2
= 169 – 25 A3 = 13 A
= 144 A1 = 5A
or A2 = 12 A2 =?
