Ammeter is a device used to measure current. Since it has to allow the complete current flowing in the circuit through it, it has to be connected in series. For this reason, ammeters have very low values of resistances so that they do not add to the value of resistance connected in the circuit.

Explanation:
Introduction:
An ammeter is a measuring instrument used to measure electric current flowing through a circuit. It is connected in series with the element through which the current is to be determined. This allows the ammeter to measure the current passing through the entire circuit.
Key Points:
1. Purpose of an Ammeter: The main purpose of an ammeter is to measure the current flowing through a circuit.
2. Connection in Series: An ammeter is always connected in series with the element through which the current is to be determined.
3. Series Connection: When connected in series, the ammeter becomes a part of the circuit through which the current is flowing.
4. Current Measurement: Since an ammeter is connected in series, it measures the same current that passes through the element it is connected to.
5. Current Divider Rule: When an ammeter is connected in series, the current flowing through the ammeter is the same as the current flowing through the element under measurement.
6. Importance of Series Connection: Connecting the ammeter in series ensures that the current flowing through the element is forced to pass through the ammeter, allowing it to measure the current accurately.
Reasoning:
To accurately measure the current flowing through a circuit, an ammeter must be connected in series with the element through which the current is to be determined. This is because when an ammeter is connected in series, it becomes a part of the circuit and measures the same current that passes through the element. Connecting the ammeter in parallel or using it to simulate the element would not provide an accurate measurement of the current.
Conclusion:
In conclusion, an ammeter is always connected in series with the element through which the current is to be determined. This connection ensures that the ammeter measures the current accurately by forcing it to pass through the ammeter.
