Reference Answer
### **Conversion of a Galvanometer into an Ammeter**
#### **1. Fundamental Principle**
A galvanometer is a highly sensitive instrument designed to detect very small electric currents, typically in the microampere or milliampere range. Its primary limitations for use as a general-purpose ammeter are:
* **High Sensitivity:** A large current would drive the pointer off-scale and potentially damage the delicate coil.
