Often called the D’Arsonval galvanometer after its inventor.
Use a labeled diagram in your PPT.
| | Disadvantages | | :--- | :--- | | High sensitivity (detects μA currents) | Can only measure DC (not AC) | | Linear scale (uniform divisions) | Requires careful leveling | | Low power consumption | Damaged by large currents (needs protection) | | Not easily affected by stray fields | Costlier than moving iron instruments |
