The instrument used to measure either direct or alternating electric current in amperes is called:
ammeter
The correct answer is ammeter.
This is so that its presence in the circuit does not change the amount of current flowing, ensuring an accurate measurement. Real ammeters have a very low internal resistance. Safety: Connecting an ammeter in parallel across a voltage source or component can cause a very large current to flow through the ammeter due to its low resistance, potentially damaging the instrument or the circuit. Understanding how to properly use an ammeter is essential for performing experiments and analyzing electrical circuits.
