1.	In a pnp-BJT, when the E-B junction is forward biased and no voltage is applied across C-B junction, what happens to the width of the depletion region in the E-B junction?(a) Increases(b) Decreases(c) Remains same(d) Can’t be determinedThe question was asked during an interview for a job.The origin of the question is BJT Construction and Operation in portion BJT Biasing of Analog Circuits
Answer» Right option is (b) Decreases To elaborate: On application of a FORWARD BIAS voltage ACROSS E-B junction, the WIDTH of the DEPLETION region decreases.
