In what configuration is an ammeter connected to a circuit?

An ammeter is connected in series with the circuit in order to measure the current flowing through that circuit accurately. By placing the ammeter in series, all the current that flows in the circuit must pass through the ammeter, allowing it to provide a direct reading of the current.

Connecting an ammeter in parallel would lead to an incorrect measurement and could damage the ammeter, as it is designed to measure current only by being part of the circuit's current pathway. This is distinct from measuring voltage, where a voltmeter would be connected in parallel to measure the potential difference across a component.

In terms of installation, positioning an ammeter in a ground context or as part of a capacitor network is not applicable for current measurement and would not yield any meaningful data about circuit current.
