Question

What is Galvanometer?​

Answer 1

Answer:

galvanometer is an instrument that can detect and measure small amounts of current in an electrical circuit. ... Essentially, a galvanometer consists of such a needle attached to a coil mounted so that the coil is allowed to pivot freely within a magnetic field created by the poles of one or more permanent magnets.

Answer 2

A galvanometer is an electromechanical measuring instrument for electric current. Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely. The galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current.
