### Step-by-Step Solution: 1. **Definition of a Shunt:** A shunt is defined as a low resistance that is connected in parallel with a circuit element. In the context of a galvanometer, it is used to allow a portion of the current to bypass the galvanometer. 2. **Purpose of a Shunt in a Galvanometer:** A galvanometer is a sensitive instrument that can detect small currents. However, it is not suitable for measuring large currents directly because it could get damaged or give inaccurate readings. To modify a galvanometer into an ammeter (which measures larger currents), a shunt is used. ...
