Question

What is the meaning of negative power factor???

Answer 1

If you have a number with a negative exponent, if that's what you mean, it would be the same as saying one divided by that number to the positive exponent.
IE) 5^-4 = 1/(5^4)
IE2) X^-1 = 1/X

Answer 2

I am an educator of fundamental circuit hypothesis in a junior college in the Southwest USA. I trust none of my understudies will see the dialog about "negative" power figure. The power calculate AC circuits has dependably been characterized as the cosine of theta; and on the other hand, as the proportion of genuine power (watts) partitioned by evident power (VA), or in fundamental circuit arrangements, the circuit resistance separated by the circuit impedance. Control variables can slack (the standard case) or driving. http://www.dissertationclub.co.uk/ written numerically the power variable is dependably a positive number somewhere around 0.0 and 1.0 (never a negative number). These ideas can be obviously appeared by drawing a diagram of the voltage and current sine waves. The power figure point (theta) speaks to a period postpone that happens in AC circuits between the voltage sine wave and the present sine wave. The diagram is typically drawn with time zero at the left hand edge and one finish sine wave indicated finishing at time 16.8 milliseconds at the correct hand edge.
