power factor for an AC ckt is given by R/{R + (XL – Xc)}^1/2
where R is resistance 
XL is inductive reactance
Xc is capacitive reactance
Hope it helps you.

Power factor=R/Z
Z=(R^2+XL^2)^1/2=(9+16)^1/2=5
Power factor=3/5=0.6 
where R is resistance 
XL is inductive reactance
Xc is capacitive reactance
Hope it helps you.
