The main difference between Galvanometer and Ammeter: A galvanometer is a sensitive instrument that detects small currents using a moving coil in a magnetic field. An ammeter is a modified galvanometer that me
Galvanometer vs Ammeter — Comparison Table
| Basis | Galvanometer | Ammeter |
|---|---|---|
| Sensitivity | Extremely sensitive to small currents | Less sensitive; measures larger currents |
| Current Range | Measures microamperes | Measures amperes or milliamperes |
| Internal Resistance | High internal resistance | Very low internal resistance |
| Modification Method | No modification from basic design | Shunt resistance added in parallel |
| Connection | Not typically used directly in circuits | Connected in series in circuits |
| Accuracy | Highly accurate for small currents | Accurate for larger current measurements |
Key Points
- A galvanometer can be converted into an ammeter by adding a shunt
- An ammeter should have very low resistance to not affect circuit current
- A galvanometer has high resistance and is not suitable for direct current measurement
- The shunt carries most of the current while galvanometer carries a small fraction
