Question
The presence of current in a circuit is detected using a __________.
- Ammeter
- Voltmeter
- Galvanometer
- Potentiometer
Hint:
Galvanometer.
The correct answer is: Galvanometer
- The presence of current is detected by a galvanometer, it shows deflections for very small magnitudes of current and we can detect the current.
- A galvanometer can be converted into an ammeter or voltmeter using a shunt resistance.
