Answer the following Increasing the current sensitivity of a galvanometer may not necessarily increases its voltage sensitivity. Explain giving reasons.

Increasing the current sensitivity of a galvanometer may not necessarily increase its voltage sensitivity. Justify this statement.

(a) Draw a labellel diagram of a moving coil galvanometer. Describe briefly its principle and working. (b) Answer the following: (i) Why is it necessary to introduce a cyclindrical soft iron core inside the coil of a galvanometer? (ii) Increasing the current sensitivity of galvanometer may not necessarily increase its voltage sensitivity. Explain, giving reason.

'Increasing the current sensitivity of galvanometer may not necessarily increases its voltage sensitivity''. Justify this statement.

Explain : "Increasing the current sensitivity may not necessarily increase the voltage sensitivity".
