Using either the Kill-a-watt VA setting or multiplying the volts times the
amps results in Volt-Amps (VA).
I was taught that A multiplied by V equals W. Is it right?
If you are measuring Direct Current, yes. But you are measuring
Alternating Current so you have to multiply the Volt-Amps by .707 to get
the actual power developed. Volt-Amps are useful in determining circuit
breaker ratings.
