3. Do Electronic ballast instead of the magnetic one in lighting save the electricity if already PF is corrected?

Even if PF is not corrected. KW is not KVA.

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...
