Answer / praveen420
No, it is not possible because
p.f=cos(angle)and cosine function is between (-1,1)....

Answer / rinto
no, it is not poosible to be the power facto more than
unity. because, cosine function has a maximum value 1 which
represents the p.f

Answer / rakesh
no, power factor can never be more than unity.
power factor is the ratio of real power delivered to the
apparent power.
=> pf = P/|S|
where P = real power,
s = complex power. s= sqrt(p^2 + q^2)
this means at most p can be equal to |s| if Q
i.e reactive power is zero.
so at most power factor can be unity.
real power (p)= v*i*cos(angle)
and apparent power = v*i
and that's why pf comes cos(angle).

Answer / shafi
No, Its not possible because cosine never more than 1
| Is This Answer Correct ? | 7 Yes | 0 No |
power factor = cosine of angle between v&I & angle cannot
be less than zero
cos0 = 1 if angle increases p.f will decrese
cos 30=0.8
cos 60=0.5
cos 0=1 there fore p.f cant be less than unity

Answer / mr.sharif
Actually P.F is related to the loads so it is not possible
for the P.F to beyond unity,If it goes beyond unity then it
is treated as power source & it is no more called as load
