Answer:

Galvanometer

Step-by-step explanation:

The device used to detect and measure current and voltage in a circuit is known as a galvanometer. It is based on the principle that a current carrying coil rotates which is suspended in a magnetic field.

Torque acts when a current carrying coil is kept in a magnetic field. It makes the needle of the galvanometer to deflect. The galvanometer is used as ammeter when a low resistance is connected in parallel and as voltmeter when high resistance is connected in series.
