Given:
A circuit
To find:
The instrument which can used to detect the presence of electric current in a circuit.
A galvanometer is that instrument which is used to detect current flowing in an electric circuit or not.
It detect the direction of current in the electric circuit.
If the galvanometer shows deflection then, the current flowing in the circuit.
If the galvanometer shows no deflection then, the current is not flowing in the circuit.
Therefore, galvanometer is that instrument which can detect the presence of electric current in a circuit.
