Question

2. The circuit shown contains three ammeters X, Y and Z.
which ammeter has the largest reading?
A X
B. Y
C. Z
D. They all have the same reading.

Answer 1

Answer:

C is the right answer

Explanation:

this is because in X and Y the current will get devided

Answer 2

Answer:

Z has the largest reading.

Explanation:

In the circuit there are two resistance 10ohm and 20ohm are connected in parallel and ammeter X is in series with 10ohm, ammeter Y is in series with 20ohm and ammeter Z is in series with the voltage source.

so, the current will divide and flow through two resistance because they are in parallel  while the total current will flow through ammeter Z becauseit is connected in series with the voltage source.

so, Z has the largest reading.
