In an electric circuit, what is the correct way to connect an ammeter?
-
A.
In series with the component
-
B.
In parallel with the component
-
C.
In parallel with the source
-
D.
In either series or parallel
Correct Answer:
A. In series with the component
Explanation:
To measure the flow of electricity accurately, an ammeter must be integrated directly into the circuit path in series with the component. This configuration ensures that the total current being measured passes through the device. Because ammeters are designed with extremely low internal resistance to prevent them from significantly altering the circuit's operation, connecting them in parallel would create a short circuit, potentially causing a dangerous surge of current that could damage the instrument or the electrical system.
