Galvanometer
An analog galvanometer is a sensitive electrical instrument used to detect and measure small electric currents in a circuit.
Key features:
-
Function: Measures very low currents, typically in the microampere (µA) range.
-
Display: Uses a needle (pointer) that moves across a calibrated scale to indicate current.
-
Working Principle: Based on the deflection of a coil suspended in a magnetic field. The current passing through the coil creates a magnetic force that moves the needle.
-
Connection: Connected in series with the circuit to measure current.
Use:
Analog galvanometers are used in physics and electronics labs to detect weak currents, demonstrate electromagnetic principles, and are sometimes adapted into voltmeters or ammeters with added components.
