Question:
An ammeter is inserted in ____.
An ammeter is inserted in ____.
Show Hint
Meter Connections. Ammeter: Connect in Series (to measure current *through* a path). Ideal R = 0. Voltmeter: Connect in Parallel (to measure voltage *across* components). Ideal R = \(\infty\).

- Series in a circuit and current to be measured flows through it
- Series in a circuit and part of the current to be measured flows through it
- Parallel in a circuit and current to be measured flows through it
- Parallel in a circuit and only part of the current to the measured flows through it. % Typo: "to the measured"

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
An ammeter is used to measure the electric current flowing through a specific point in a circuit
To measure this current, the ammeter must be inserted *into* the path of the current, meaning it must be connected in series with the component(s) through which the current is flowing
When connected in series, the entire current that is being measured passes through the ammeter
Connecting an ammeter in parallel would bypass the current around the meter (due to its ideally low resistance) and potentially damage it
Option (1) correctly describes the series connection and the flow of the measured current through the instrument
Option (2) is incorrect because ideally, all the current being measured should flow through the series-connected ammeter (or the total current splits between the movement and shunt within the ammeter)
