4. ### what is the pf of transformer?

With no load, the power factor of a transformer is very low, but it not zero. The current always has a real component because of power losses in the transformer. The copper losses go down in proportion to current squared, but the iron losses are not...

10. ### What is the capacitance in pF?

sure it is working, you just need to keep track of units - in metric system, unit of length is meter, not cm, mm, km etc. so A=0.03x0.03=0.0009 m^2 D=0.0007 m ε0 ≈ 8.854187817620... × 10−12 F/m or ε0 ≈ 0.000000000008854187817620 F/m you get C=1.1384x10...
