How are ammeters connected in an electrical circuit?

Ammeters are designed to measure the current flowing through a circuit, and they must be connected in series with the circuit to achieve this. When connected in series, the ammeter becomes part of the current path, allowing all the current to flow through it. This setup ensures that the meter can accurately measure the amount of current in amperes since the same current flows through every component in a series circuit.

This configuration contrasts with other measuring devices, such as voltmeters, which are connected in parallel to measure voltage. If an ammeter were connected in parallel, it would create a short circuit, potentially damaging the meter and leading to inaccurate readings.
