In which configuration should ammeters and voltmeters be connected respectively?

Ammeters are designed to measure current by being connected in series within the circuit. This connection allows the entire current flowing through the circuit to pass through the ammeter, providing an accurate measurement of the current value. If an ammeter were connected in parallel, it could create a short circuit, potentially damaging the meter and affecting circuit operation.

Voltmeters, on the other hand, are used to measure the potential difference (voltage) across two points in a circuit and must be connected in parallel. This configuration ensures that the voltmeter measures the voltage across the same two points without affecting the current in the circuit. Connecting a voltmeter in series would effectively open the circuit and prevent current from flowing, resulting in no voltage measurement.

Therefore, the correct configuration is to connect ammeters in series and voltmeters in parallel to ensure accurate readings and proper circuit functionality.
