A galvanometer is used in devices that measure electric current. It is commonly found in:
1. **Analog Multimeters**: Used for measuring voltage, current, and resistance.
2. **Ammeter**: Specifically designed to measure current in a circuit.
3. **Wattmeters**: Used to measure power in an electrical circuit.
4. **Oscilloscopes**: In older models, galvanometers were used for deflecting beams to display waveforms.
5. **Scientific Equipment**: In laboratories for experiments involving current measurement.
Galvanometers can also be part of systems for measuring electrical signals in various applications.
