Milliammeter
An analog milliammeter is an electrical measuring instrument used to measure electric current in the milliampere (mA) range.
Key features:
-
Measurement Range: Typically measures currents from 1 mA to a few hundred mA.
-
Display: Features a needle (pointer) that moves over a graduated scale to indicate current.
-
Type: Analog, meaning it uses mechanical movement
-
Connection: Connected in series with the circuit so the current flows through the device.
-
Working Principle: Operates based on the deflection of a moving coil in a magnetic field, similar to a galvanometer.
Use:
Commonly used in electronics labs and educational settings to monitor and measure small electrical currents in circuits and devices. It provides a simple, real-time visual indication of current flow.
