When connecting an Ammeter, how should the coils be arranged?

An ammeter is designed to measure the current flowing through a circuit, and to do so effectively, it must be connected in series with the load. When connected in series, the entire current of the circuit passes through the ammeter, allowing it to provide an accurate measurement of the electrical current.

The series connection ensures that the ammeter becomes a part of the circuit, which means it can measure the current accurately without influencing the overall operation of the circuit. If an ammeter were connected in parallel or in configurations like a loop or grid, it could significantly affect the current reading and potentially damage the ammeter due to excessive current flow.

By arranging the coils in series, the ammeter operates as intended — as a device to measure the amount of current in a straightforward and effective manner. Understanding this basic principle is critical for anyone working with electrical circuits, as correct ammeter usage is foundational for safe and accurate measurements.
