Question

B. Increasing the current sensitivity of a galvanometer may not necessary increase its voltage sensitivity. Explain giving reasons

Answer 1

Current sensitivity does not depend upon resistance(R), whereas voltage sensitivity does, as evident from their expressions. Current sensitivity can be increased by increasing the number of turns of the coil. However, this increases the resistance of the coil also(R is proportional to length of conductor).
