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.

Explanation

### Step-by-Step Solution

**Step 1: State the underlying principle of working of a moving coil galvanometer.**

The moving coil galvanometer operates on the principle that a current-carrying conductor placed in a magnetic field experiences a magnetic force. This force causes the coil to rotate, which is then indicated by a pointer on a scale.

**Step 2: Explain why a galvanometer cannot be used as such to measure current in a given circuit.**
