PhysicsEasysingle choice

A transistor is operated in common emitter configuration at $V_{C} = 2 V$ such that a change in the base current from $100 μ A$ to $300 μ A$ produces a change in the collector current from $10 mA$ to $20 mA$ . The current gain isNEET 2011 (Screening)

Options:

Answer:

Solution:

$β = \frac{Δ I _{C}}{Δ I _{B}} = \frac{( 20 - 10 ) mA}{( 300 - 100 ) mA} = \frac{10 \times 1 0 ^{- 3}}{200 \times 1 0 ^{- 6}} = 50$
