14.6 In half-wave rectification, what is the output frequency if the input frequency is 50 Hz. What is the output frequency of a full-wave rectifier for the same input frequency.

The correct statement (b), (c).

for a transistor action, the junction must be lightly doped so thatthe hase reon is very thin. Also, the emitter junction must be

forward-biased and collector junction should be reverse- biased.
