Voltmeter and Ammeter are the basic need of each and everyone who is want to start the project with the help of electronic products. A voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit.
A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current. Ammeters work to measure electrical current by measuring the current through a set of coils with very low resistance and inductive reactance
