A purely resistive load consumes 1440 watts at 120 volts RMS AC (power factor 1). What RMS current does it draw?
Correct Answer
D) 12 amps.
With power factor 1, I = P/V = 1440/120 = 12 amperes. This calculates load current only, not the permitted branch-circuit loading or breaker size.
Why This Is the Correct Answer
With power factor 1, I = P/V = 1440/120 = 12 amperes. This calculates load current only, not the permitted branch-circuit loading or breaker size.
