Two Marks Questions 1. In a transistor having finite β, the forward bias across the base emitter junction

Question

In a transistor having finite β, the forward bias across the base emitter junction is kept constant and the reverse bias across the collector base junction is increased. Neglecting the leakage across the collector base junction and the depletion region generations current, the base current will _________ (increase / decrease / remains constant)

Answer 1

As the reverse bias at the collector base junction is increased, the effective base width decreases, so the recombination in base will decrease. This will reduce base current (I_B)
