Question

q.12. in the following circuit the current at ammeter x is 2.0 a, what is the reading on ammeter y?
circuit diagram with ammeter x, ammeter y, two bulbs, battery, switch
a) 1.0 a
b) 2.0 a
c) 3.0 a
d) 4.0 a

Explanation:

Step1: Identify the circuit type

The circuit is a series circuit (components connected in a single path).

Step2: Recall series circuit current rule

In a series circuit, the current is the same at all points. So if ammeter X reads 2.0 A, ammeter Y (in the same series path) will also read 2.0 A.

Answer:

b) 2.0 A
