Electronic wattmeter
... The result of this arrangement is that on a dc circuit, the deflection of the needle is proportional to both the current and the voltage, thus conforming to the equation W=VA or P=VI. For AC power, current and voltage may not be in phase, owing to the delaying effects of circuit inductance or capac ...

... 4.04 The SNIX and QUIK-SNIX will limit longitudinal AC voltages-to-ground up to 30 volts AC. The Super SNIX will suppress up to 50 volts AC. Voltages above these values may cause the SNIXs to saturate, which can increase the AC voltage or generate noise on the circuit. 4.05 All SNIXs and Super SNIXs ...
