The circuits were designed using two A/D converters to create a voltmeter and ampermeter. The circuits are designed with the combination of CA3161E and CA3162E to imposing a complete 3-digit display ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

The current coil of wattmeter is connected in series with an ammeter and an inductive load. A voltmeter and the voltage circuit of the wattmeter are connected across a 400-Hz supply. The ammeter ...
