What is the true power for a 16 amp load operating at 120 volts with a power factor of 85%?

Volt-Amps = Apparent power = volts * amps
Watts = True power = volts * amps * power factor
Volt-Amps-reactive = Reactive power
120 volts * 16 amps = 1920 VA apparent power
1920 * .85 = 1632 watts
Picture a right triangle with a base labeled "real power" (W) and a hypotenuse labeled "apparent power" or VA. The opposite side of the triangle is labeled "reactive power" or VAr.
The cosine of the angle is the power factor: arccos .85 = 32°

100% power = 16 x 120 = 1920 Watts.
85% = 1920 x 0.85 = 1632 Watts.

W = 16*120*0.85 w =1632 watt

power = Current * voltage * power factor
p = 16 * 120 * .85
p = 1632 w
hope I helped
