Question
What is that instrument which can detect the presence of electric current in a circuit?
- Galvanometer
- Ammeter
- Voltmeter
- None of the above
Hint:
A galvanometer is used to determine the presence of electric current in a circuit.
The correct answer is: Galvanometer
- The electric current in a circuit is measured by an ammeter.
- The name "ammeter" comes from the fact that the device measures current in amperes. We can detect any change in an electric current in the circuit using a galvanometer.
- In bridges, it is frequently used to monitor zero current.
