It is not possible to make a pure inductor,why?

a pure semiconductor

Pure silicon should be doped with which of the foll. Impurity atoms to make a p-type semiconductor?

Why is there no power loss in an inductor?

Show that in an AC circuit containing a pure inductor,the voltage is ahead of current by pi/2 in phase.

For very high frequency AC supply, a capacitor behaves like a pure conductor. Why?

Draw the pairs of angles as described below. If that is not possible, say why ? Complementary angles which are not adjacent.

Draw the pairs of angles as described below. If that is not possible, say why ? Angles which are neither complementarian nor adjacent.

Draw the pairs of angles as described below. If that is not possible, say why ? Supplementary angles which are not angles in linear pair.

Draw the pairs of angles as described below. If that is not possible, say why ? Adjacent angles which are not in a linear pair.

Define power factor.Write its value for pure inductor.
