Name the tool which is used to measure the current in any electronic circuit. Correct Answer Ammeter
Ammeter:
- The meter used for measuring the current is known as the ammeter.
- The current is the flow of electrons whose unit is ampere.
- Hence the instrument which measures the flows of current in an ampere is known as the ampere meter or ammeter.

Connection of Ammeter in Circuit:
- It is connected in series with the circuit so that the whole electrons of the measurand current pass through the ammeter.
- The power loss occurs in the ammeter because of the measurand current and their internal resistance.
- The ammeter circuit has low resistance so that a small voltage drop occurs in the circuit.

The resistance of the ammeter is kept low because of the two reasons:
- The whole measure current passes through the ammeter.
- The low voltage drop occurs across the ammeter.
