What is Ammeter? and Explain its Types and Applications

WebbCurrent sensor. A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be analog voltage or current or a digital output. The generated signal can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data … WebbSince current always creates a magnetic field, there are Hall Effect and other sensors that allow us to measure this field and thereby measure the current. It is also possible to connect a shunt resistor within the circuit itself and directly measure the current, as in the classic ammeter and current shunt. WebbThe ammeter shunt is used to divert most of the circuit current towards shunt resistance and fraction of current towards the ammeter. Total resistance of the circuit (R) = 4+ (200 … chinese bows
