Question
What is that instrument which can detect the presence of electric current in a circuit?
- Voltmeter
- Generator
- Ammeter
- Galvanometer
Hint:
The galvanometer is an instrument used to measure the presence of current.
The correct answer is: Galvanometer
Galvanometer is that instrument which can detect the presence of electric current in a circuit.
- The presence of electric current in a circuit can be detected by using the galvanometer.
- It detects the direction of current with a deflection of a small moving coil.
- Small amounts of current can be detected by the galvanometer.
- Both the direction and magnitude of the small current of the order of micro-amperes are detected by this instrument.
