Question

8. A moving-coil galvanometer has its coil of 24 turns
and 12 12 resistance. By how much the number
ex
of turns should be increased so that the current-
sensitivity of the galvanometer increases by 25%?
If, in doing so, the resistance of the coil increases to
2012, what will be the effect on the voltage-sensitivity of
the galvanometer?
from 1 to 20.​

Answer 1

Answer:

therefore the turns increase from 24 to 30 and voltage resistivity will fall by 25 percentage .

i hope this helps
