Question

What are the limitations of dead beat galvanometer ?

Answer 1

Now, when the coil oscillates, eddy currents are set up in a metallic frame, which opposes further oscillations of the coil. This inturn enables the coil to attain its equilibrium position almost instantly. Since the oscillations of the coil die out instantaneously, the galvanometer is called dead beat galvanometer.

Answer 2

Answer:

it is bulky and its sensitive does not decrease with certain limit.
