A Galvanometer is a precision instrument used to detect and measure small electric currents. It operates based on the interaction between a magnetic field and a current-carrying coil, producing a deflection proportional to the current.
Key Features:
• High Sensitivity: Detects minute currents, typically in microamperes or milliamperes.
• Analog Display: Provides a needle-based deflection for visual representation of current flow.
• Low Power Consumption: Requires minimal current for operation.
• Versatile Applications: Used in physics experiments, electrical circuit testing, and as a component in other measuring instruments like ammeters and voltmeters.
Galvanometers are essential tools in laboratories, educational settings, and precision instrumentation, making them ideal for measuring weak electrical signals.
