How is an ammeter connected in a circuit?

An ammeter is designed to measure the current flowing through a circuit, and for it to accurately perform this function, it must be connected in series with the circuit. When connected in series, the ammeter allows all the current that is flowing through the circuit to pass through it, enabling it to make a precise measurement of that current.

Connecting the ammeter in parallel with a load would create a short circuit, which could damage the ammeter and result in inaccurate readings or circuit failure. Similarly, while connecting across the load or in a loop might imply an alternate pathway for current, it would not facilitate the correct measurement of the current in the primary circuit. Thus, connecting an ammeter in series is essential for precise current measurements in electrical applications.
