Question

Why do I get a negative power factor?

Answer 1

Power factor can never be negative because it is the cosine of angle b/w voltage and current. Power Factor is leading or lagging that depends upon what kind of load is connected in the circuit when load is more inductive current lags and u get lagging power factor and when there is more capacitive load u get leading power factor.

Answer 2

if you calculated this using: power factor=(average power)/(apparent power)
then remember that when you are finding the apparent power you have to multiply the voltage with the CONJUGATE OF THE CURRENT... you might have gone wrong there....... can you actually post the question up, so we can work it out for you

Answer 3

i hope if a source consume power then angle between voltage and current will be more than 90 degree. i.e. power factor will be negative. simply negative power factor means absorbation of power.

Answer 4

I think there is no active or passive element which provides you phase difference greater than 90 degree.
