  1. 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...

  6. Varactor characteristics aren't linear http://spraguegoodman.com/pdfs/950.pdf The only way to plot a curve would be to either do an actual Vr versus capacitance or simulate it on one of the many electronic simulation programs. Assuming you meant 200μ...

  7. Initial charge is Q = CV = 19.2 nC Mica has a dielectric constant of about 7 (varies a lot, depending on type and source) so the capacitance changes to 2.4 nF x 7 = 16.8 nF new charge is 16.8 nF x 8 = 134...

  8. The first answer is correct. If you really need other answers, you can combine 9 caps in parallel and then put 6 sets of them in series. Or 18 caps and 12 sets. There are an infinite number of...
