The sensitivity of a galvanometer depends on

Name any two factors on which the current sensitivity of a galvanometer depends.

State the underlying principles of working of a moveing coil galvanometer. Write the two reasons why a galvonmeter cannot be used as such to measure current in a given circuit.Name any two factors on which that current sensitivity of a galvanometer depends.

The sensitivity of a galvanometer does not depend upon

The sensitivity of a galvanometer is 60 division /A . When a shunt is used, its sensitivity becomes 10 division/A. If the galvanometer is of resistance 20 Omega , the value of shunt used is

The current sensitivity of a galvanometer increases by 20%. If its resistance also increases by 25%, the voltage sensitivity will
