What type of resistance is preferred for an ammeter to function properly?

For an ammeter to function properly, it is essential that it has a low resistance. The primary purpose of an ammeter is to measure the current flowing through a circuit, and it needs to be connected in series within that circuit. If the ammeter had high resistance, it would significantly impede the flow of current, potentially altering the measurements and leading to inaccurate readings.

By having low resistance, the ammeter allows the current to pass through it with minimal obstruction, ensuring that it accurately reflects the actual current in the circuit. This design helps maintain the integrity of the circuit's operation while enabling precise measurements. Therefore, low resistance is critical for the correct and effective functioning of an ammeter in any electrical measurement scenario.
